	Basis of Presentation
	The accompanying unaudited consolidated financial statements have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (SEC). Certain information and note disclosures normally included in the annual financial statements, prepared in accordance with accounting principles generally accepted in the United States of America, have been condensed or omitted pursuant to those rules and regulations. We recommend that you read these unaudited consolidated financial statements in conjunction with the audited consolidated financial statements and related notes included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2013, previously filed with the SEC. We believe that the unaudited consolidated financial statements in this Form 10-Q reflect all adjustments that are necessary to fairly present the financial position, results of operations and cash flows for the interim periods presented. The results of operations for such interim periods are not necessarily indicative of the results that can be expected for the full year.
	We classify indirect cost incurred as cost of services and general and administrative expenses in the same manner as such costs are defined in our disclosure statements under U.S. Government Cost Accounting Standards. Effective January 1, 2014, we updated our disclosure statements with the Defense Contract Management Agency, resulting in certain costs being classified differently either as cost of services or as general and administrative expenses on a prospective basis. This change has caused a net increase in the reported cost of services and a net decrease in reported general and administrative expenses in 2014 as compared to 2013; however, total operating costs were not affected by this change.

	Acquisitions
	7Delta Inc.—On May 23, 2014, we completed the acquisition of all equity interests in 7Delta Inc. (7Delta). The results of 7Delta's operations have been included in our consolidated financial statements since that date. The acquisition was completed through an amended and restated stock purchase agreement dated May 23, 2014, by and among ManTech International Corporation, 7Delta, SLS Holdings, Inc. and the stockholders of SLS Holdings, Inc. 7Delta performs critical services such as applications and software development, program management, systems integration, information assurance and security architecture primarily within the healthcare community at the Department of Veteran Affairs (VA). We funded the acquisition through a combination of cash on hand and borrowings under our revolving credit facility. The stock purchase agreement did not contain provisions for contingent consideration.
	During the six months ended June 30, 2014, ManTech incurred approximately $0.6 million of acquisition costs related to the 7Delta transaction, which are included in the general and administrative expenses in our consolidated statement of income.
	The preliminary purchase price of $80.0 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The preliminary purchase price may increase or decrease depending on the completion of the working capital adjustment. We are still in the process of reviewing the working capital accounts at the date of acquisition for potential adjustments to the purchase price and the determination of the fair value of the assets acquired and liabilities assumed. We preliminarily recorded goodwill of $69.6 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for 7Delta's capabilities in providing software development, program management, system integration, information assurance and security architecture to the VA.
	In preliminarily allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of 7Delta's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $4.8 million and $2.9 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with 7Delta's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful life of approximately 10 years. Backlog is amortized straight-line over its estimated useful life of 2 years. The weighted-average amortization period for the intangible assets is 7.0 years.
	We have not disclosed current period, nor pro forma, revenues and earnings attributable to 7Delta as our integration of these operations post acquisition and the entity's accounting methods preacquisition make it impracticable.
	Allied Technology Group, Inc.—On February 18, 2014, we completed the acquisition of all equity interests in Allied Technology Group, Inc. (ATG). The results of ATG's operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated February 18, 2014, by and among ManTech Advanced Systems International, Inc., Allied Technology Group, Inc. and the stockholders of ATG. ATG is an innovative engineering and information management solution company with strong customer relationships and strategic contracts with the Department of Homeland Security (DHS). ATG provides IT, engineering services, program management and training solutions to a variety of federal customers. The acquisition will enable us to deliver services through their unrestricted prime position on DHS's primary acquisition vehicles: Technical, Acquisition and Business Support Services and Enterprise Acquisition Gateway for Leading Edge Solutions II. We funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration.
	During the six months ended June 30, 2014, ManTech incurred approximately $0.4 million of acquisition costs related to the ATG transaction, which are included in the general and administrative expenses in our consolidated statement of income.
	The purchase price of $45.0 million was preliminarily allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. We are still evaluating the fair value of assets acquired and liabilities assumed. We preliminarily recorded goodwill of $28.4 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for ATG's capabilities in providing technology service program management, systems engineering and information technology services to DHS.
	In preliminarily allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of ATG's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $6.4 million and $0.6 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with ATG's existing customers. Customer relationships are amortized using the pattern of benefits method over their estimated useful life of approximately 20 years. Backlog is amortized straight-line over its estimated useful life of 1 year. The weighted-average amortization period for the intangible assets is 18.4 years.
	We have not disclosed current period, nor pro forma, revenues and earnings attributable to ATG as our integration of these operations post acquisition and the entity's accounting methods preacquisition make it impracticable.

	ALTA Systems, Inc.—On January 8, 2013, we completed the acquisition of all equity interests in ALTA Systems, Inc. (ALTA). The results of ALTA's operations have been included in our consolidated financial statements since that date. The acquisition was completed through a stock purchase agreement dated January 8, 2013, by and among ManTech International Corporation, ALTA Holdings LLC and the sole member of ALTA Holdings LLC. ALTA is an information technology (IT) and professional services company with valuable applications in healthcare systems and capital planning. ALTA provides a broad range of IT and professional services to government and private industry in three major areas: capital planning and investment control; system design, development and operations; and fraud detection and statistical analysis. The acquisition allows ManTech to deliver technology services through ALTA's prime position on the Centers for Medicare and Medicaid Services (CMS) Enterprise Systems Development (ESD) contract. ManTech funded the acquisition with cash on hand. The stock purchase agreement did not contain provisions for contingent consideration.
	During the six months ended June 30, 2013, ManTech incurred approximately $0.1 million of acquisition costs related to the ALTA transaction, which are included in the general and administrative expenses in our consolidated statement of income.
	The purchase price of $10.2 million was allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. We have recorded total assets of $11.1 million, including goodwill and intangible assets recognized in connection with the acquisition, and total liabilities of $0.9 million. Included in total assets were $0.7 million in acquisition related intangible assets. We recorded goodwill of $9.1 million, which will be deductible for tax purposes over 15 years, assuming adequate levels of taxable income. Recognition of goodwill is largely attributed to the value paid for ALTA's capabilities in providing technology services to the federal government in the health care sector.
	In allocating the purchase price, we considered among other factors, analysis of historical financial performance and estimates of future performance of ALTA's contracts. The components of other intangible assets associated with the acquisition were customer relationships and backlog valued at $0.6 million and $0.1 million, respectively. Customer contracts and related relationships represent the underlying relationships and agreements with ALTA's existing customers. Customer relationships and backlog are amortized straight-line over their estimated useful lives of approximately 20 years and 1 year, respectively. The weighted-average amortization period for the intangible assets is 17.1 years.

Earnings Per Share [Abstract]	'
Earnings Per Share [Text Block]	'
	Earnings Per Share
	Under ASC 260, Earnings per Share, the two-class method is an earnings allocation formula that determines earnings per share for each class of common stock according to dividends declared (or accumulated) and participation rights in undistributed earnings. Under that method, basic and diluted earnings per share data are presented for each class of common stock.
	In applying the two-class method, we determined that undistributed earnings should be allocated equally on a per share basis between Class A and Class B common stock. Under the Company’s Certificate of Incorporation, the holders of the common stock are entitled to participate ratably, on a share-for-share basis as if all shares of common stock were of a single class, in such dividends, as may be declared by the Board of Directors. During each of the six months ended June 30, 2014 and 2013, we declared and paid two quarterly dividends in the amount of $0.21 per share on both classes of common stock.
	Basic earnings per share has been computed by dividing net income available to common stockholders by the weighted average number of common shares outstanding during each period. Shares issued during the period and shares reacquired during the period are weighted for the portion of the period in which the shares were outstanding. Diluted earnings per share has been computed in a manner consistent with that of basic earnings per share while giving effect to all potentially dilutive common shares that were outstanding during each period.
	The net income available to common stockholders and weighted average number of common shares outstanding used to compute basic and diluted earnings per share for each class of common stock are as follows (in thousands, except per share amounts):

	For the three months ended June 30, 2014 and 2013, options to purchase 2.8 million and 3.3 million shares, respectively, were outstanding but not included in the computation of diluted earnings per share because the options’ effect would have been anti-dilutive. For the six months ended June 30, 2014 and 2013, options to purchase 2.8 million and 3.5 million shares, respectively, were outstanding but not included in the computation of diluted earnings per share because the options’ effect would have been anti-dilutive. For the six months ended June 30, 2014 and 2013, shares issued from the exercise of stock options were 53 thousand and 39 thousand, respectively.

	Amounts billable consist principally of amounts to be billed within the next month. Revenues recorded in excess of funding are billable upon receipt of contractual amendments or other modifications. The retainage is billable upon completion of contract performance and approval of final indirect expense rates by the government. There is a contract with the U.S. Army that represents 10.9% and 15.3% of receivables-net at June 30, 2014 and December 31, 2013, respectively. Accounts receivable at June 30, 2014, are expected to be substantially collected within one year except for approximately $1.4 million, of which amount 91.1% is related to receivables from direct sales to the U.S. government. The remainder is related to receivables from contracts in which we acted as a subcontractor to other contractors.
	The Company does not believe it has significant exposure to credit risk as accounts receivable and the related unbilled amounts are primarily due from the U.S. government. The allowance for doubtful accounts represents the Company’s exposure to compliance issues, contractual issues and bad debt related to prime contractors.

	Goodwill and Other Intangible Assets
	Under ASC 350, Intangibles—Goodwill and Other, goodwill is to be reviewed at least annually for impairment and whenever events or circumstances indicate that the carrying value of goodwill may not be fully recoverable. We have elected to perform this review during the second quarter of each calendar year. An entity may assess qualitative factors to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. An entity has an unconditional option to bypass the qualitative assessment for any reporting unit in any period and proceed directly to performing the first step of the goodwill impairment test. An entity may resume performing the qualitative assessment in any subsequent period. The first step of the goodwill impairment test compares the fair value of a reporting unit with its carrying amount (including goodwill). If the reporting unit's fair value exceeds its carrying value, no further procedures are required. However, if the reporting unit's fair value is less than its carrying value, an impairment of goodwill may exist, requiring a second step to be performed. Step two of this test measures the amount of the impairment loss, if any. Step two of this test requires the allocation of the reporting unit's value to its assets and liabilities, including any unrecognized intangible assets, in a hypothetical analysis that calculates the implied fair value of the goodwill as if the reporting unit were being acquired in a business combination. If the implied fair value of goodwill is less than the carrying value, the difference is recorded as a goodwill impairment charge in operations.
	The fair values of the reporting units are determined based on a weighting of the income approach, market approach and market transaction approach. The income approach is a valuation technique in which fair value is calculated based on forecasted future cash flow discounted at the appropriate rate of return commensurate with the risk as well as current rates of return for equity and debt capital as of the valuation date. The forecast used in our estimation of fair value was developed by management based on a contract basis, incorporating adjustments to reflect known contract and market considerations (such as reductions and uncertainty in government spending, pricing pressure and opportunities). The discount rate utilizes a risk adjusted weighted average cost of capital. The market approach is a valuation technique in which the fair value is calculated based on market prices realized in actual arm's length transactions. The technique consists of undertaking a detailed market analysis of publicly traded companies that provides a reasonable basis for comparison to the company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and other factors. The market transaction approach is a valuation technique in which the fair value is calculated based on market prices realized in actual arm's length transactions. The technique consists of undertaking a detailed market analysis of merged and acquired companies that provided a reasonable basis for comparison to the company. Valuation ratios, which relate market prices to selected financial statistics derived from comparable companies, are selected and applied to the company after consideration of adjustments for financial position, growth, market, profitability and other factors. To assess the reasonableness of the calculated reporting unit fair values, we compare the sum of the reporting units' fair values to the Company's market capitalization (per share stock price times the number of shares outstanding) and calculate an implied control premium, which we then compare to the control premiums in comparable transactions to assess the reasonableness of our calculations.
	During the second quarter of 2014, we completed our annual goodwill impairment test. The results of this test indicated that the fair values of all reporting units were substantially in excess of their carrying values, therefore, no impairment losses were identified and performance of step two was not required. We continue to monitor events that could impact our financial outlook and our assets including potential significant reductions in government spending that could adversely impact our financial results and changes in market conditions that could result in a reduction in the fair value of our assets.
	The changes in the carrying amounts of goodwill during the year ended December 31, 2013 and the period ended June 30, 2014 are as follows (in thousands):

	Revolving Credit Facility—We maintain a credit facility with a syndicate of lenders led by Bank of America, N.A, as sole administrative agent. The credit agreement provides for a $500 million revolving credit facility, with a $25 million letter of credit sublimit and a $30 million swing line loan sublimit. The credit agreement also includes an accordion feature that permits the Company to arrange with the lenders for the provision of additional commitments. On June 13, 2014, we amended and restated the credit agreement, and extended the maturity date to June 13, 2019. We deferred $3.4 million in debt issuance costs, which are amortized over the term of the amended and restated credit agreement.
	Borrowings under our revolving credit facility are collateralized by substantially all the assets of ManTech and its Material Subsidiaries (as defined in the credit agreement) and bear interest at one of the following variable rates as selected by the Company at the time of borrowing: a London Interbank Offer Rate (LIBOR) base rate plus market-rate spreads (1.25% to 2.25% based on the Company's consolidated total leverage ratio) or Bank of America's base rate plus market spreads (0.25% to 1.25% based on the Company's consolidated total leverage ratio).
	The terms of the credit agreement permit prepayment and termination of the loan commitments at any time, subject to certain conditions. The credit agreement requires the Company to comply with specified financial covenants, including the maintenance of certain leverage ratios and a certain consolidated coverage ratio. The credit agreement also contains various covenants, including affirmative covenants with respect to certain reporting requirements and maintenance of certain business activities, and negative covenants that, among other things, may limit or impose restrictions on our ability to incur liens, incur additional indebtedness, make investments, make acquisitions, and undertake certain other actions. As of June 30, 2014, we were in compliance with the financial covenants under the credit agreement.
	The outstanding balance on our revolving credit facility at June 30, 2014 and December 31, 2013 was $55.0 million and $0, respectively. The outstanding debt balance at June 30, 2014 is estimated to be repaid by June 30, 2015. The maximum available borrowing under our revolving credit facility at June 30, 2014 was $444.2 million. As of June 30, 2014, we were contingently liable under letters of credit totaling $0.8 million, which reduced our availability to borrow under our revolving credit facility.
	7.25% Senior Unsecured Notes—On April 15, 2014, we paid the redemption price plus accrued and unpaid interest on our 7.25% senior unsecured notes issued on April 13, 2010 for $200.0 million, which were registered under the Securities Act of 1933. The 7.25% senior unsecured notes were redeemed, at a redemption price of 103.625% of the principal amount of the outstanding 7.25% senior unsecured notes, or $207.3 million. As a result of the redemption of our 7.25% senior unsecured notes, we recorded a loss on the extinguishment of debt for $10.1 million as non-operating income on our consolidated statement of income.

	Commitments and Contingencies
	Contracts with the U.S. government, including subcontracts, are subject to extensive legal and regulatory requirements and, from time to time, agencies of the U.S. government, in the ordinary course of business, investigate whether the Company’s operations are conducted in accordance with these requirements and the terms of the relevant contracts. U.S. government investigations of the Company, whether related to the Company’s U.S. government contracts or conducted for other reasons, could result in administrative, civil, or criminal liabilities, including repayment, fines or penalties being imposed upon the Company, or could lead to suspension or debarment from future U.S. government contracting activities. Management believes it has adequately reserved for any losses that may be experienced from any investigation of which it is aware. We have settled all incurred cost submissions through 2005 with the Defense Contract Management Agency (DCMA) Corporate Administrative Contracting Officer (CACO). Settlements of the 2006 through 2013 incurred cost submission are not expected to have a material effect on our financial position, results of operations or cash flow, and management believes it has adequately reserved for any losses.
	In the normal course of business, we are involved in certain governmental and legal proceedings, claims and disputes and have litigation pending under several suits. We believe that the ultimate resolution of these matters will not have a material effect on our financial position, results of operations or cash flows.

	Stock-Based Compensation
	Our 2011 Management Incentive Plan (the Plan) was designed to attract, retain and motivate key employees. Awards granted under the Plan are settled in shares of Class A common stock. At the beginning of each year, the Plan provides that the number of shares available for issuance automatically increases by an amount equal to 1.5% of the total number of shares of Class A and Class B common stock outstanding on December 31st of the previous year. On January 2, 2014, 557,894 additional shares were made available for issuance under the Plan. Through June 30, 2014, the remaining aggregate number of shares of our common stock authorized for issuance under the Plan was 4,068,523. Through June 30, 2014, there were 4,707,168 shares of our Class A common stock that were issued and remain outstanding as a result of equity awards granted under the Plan. The Plan expires in May 2021.
	The Plan is administered by the compensation committee of our Board of Directors, along with its delegates. Subject to the express provisions of the Plan, the committee has the Board of Directors’ authority to administer and interpret the Plan, including the discretion to determine the exercise price, vesting schedule, contractual life and the number of shares to be issued.
	Stock Compensation Expense—For the three months ended June 30, 2014 and 2013, we recorded $1.0 million and $1.4 million of stock-based compensation expense, respectively. For the six months ended June 30, 2014 and 2013, we recorded $2.2 million and $2.8 million of stock-based compensation expense, respectively. No compensation expense of employees with stock awards, including stock-based compensation expense, was capitalized during the periods. For the six months ended June 30, 2014 and 2013, the total recognized tax deficiency from the exercise of stock options, vested cancellations and the vesting of restricted stock was $1.9 million and $1.3 million, respectively.
	Stock Options—We typically issue options that vest over three years in equal annual installments beginning on the first anniversary of the date of grant. Under the terms of the Plan, the contractual life of the option grants may not exceed eight years. During the six months ended June 30, 2014 and 2013, we issued options that expire five years from the date of grant.
	Fair Value Determination—We have used the Black-Scholes-Merton option pricing model to determine fair value of our awards on the date of grant. We will reconsider the use of the Black-Scholes-Merton model if additional information becomes available in the future that indicates another model would be more appropriate or if grants issued in future periods have characteristics that cannot be reasonably estimated under this model.
	The following weighted-average assumptions were used for option grants during the six months ended June 30, 2014 and 2013:
	Volatility—The expected volatility of the options granted was estimated based upon historical volatility of the Company’s share price through weekly observations of the Company’s trading history.
	Expected Term—The expected term of options granted to employees during the six months ended June 30, 2014 and 2013 was determined from historical exercises of the grantee population. For all grants valued during the six months ended June 30, 2014 and 2013, the options had graded vesting over three years in equal annual installments beginning on the first anniversary of the date of grant and a contractual term of five years.
	Risk-free Interest Rate—The yield on zero-coupon U.S. Treasury strips was used to extrapolate a forward-yield curve. This “term structure” of future interest rates was then input into a numeric model to provide the equivalent risk-free rate to be used in the Black-Scholes-Merton model based on the expected term of the underlying grants.
	Dividend Yield—The Black-Scholes-Merton valuation model requires an expected dividend yield as an input. We have calculated our expected dividend yield based on an expected annual cash dividend of $0.84 per share.
	The following table summarizes weighted-average assumptions used in our calculations of fair value for the six months ended June 30, 2014 and 2013:
		Six months ended
		June 30,
		2014		2013
	Volatility	29.88	%	32.45	%
	Expected life of options	3 years		3 years
	Risk-free interest rate	0.85	%	0.44	%
	Dividend yield	3	%	3	%
	Stock Option Activity—During the six months ended June 30, 2014, we granted stock options to purchase 492,004 shares of Class A common stock at a weighted-average exercise price of $29.17 per share, which reflects the fair market value of the shares on the date of grant. The weighted-average fair value of options granted during the six months ended June 30, 2014 and 2013, as determined under the Black-Scholes-Merton valuation model, was $4.90 and $4.81, respectively. These options vest over three years in equal annual installments beginning on the first anniversary of the date of the grant and have a contractual term of five years. Option grants that vested during the six months ended June 30, 2014 and 2013 had a combined fair value of $2.6 million and $3.9 million, respectively.
	The following table summarizes stock option activity for the year ended December 31, 2013 and the six months ended June 30, 2014:

	Stock options exercisable and expected to vest	3,143,198
	Unrecognized compensation expense related to outstanding stock options expected to vest as of June 30, 2014 was $5.5 million, which is expected to be recognized over a weighted-average period of 1.9 years and will be adjusted for any future changes in estimated forfeitures.
	Restricted Stock—Under the Plan, we have issued restricted stock. A restricted stock award is an issuance of shares that cannot be sold or transferred by the recipient until the vesting period lapses. Restricted shares issued to employees vest over three years in equal annual installments beginning on the first anniversary of the grant date, contingent upon employment with the Company on the vesting dates. Restricted shares issued to members of our Board of Directors vest in one year. The related compensation expense is recognized over the service period and is based on the grant date fair value of the stock and the number of shares expected to vest.

	We have one reportable segment. We deliver a broad array of information technology and technical services solutions under contracts with the U.S. government. Our federal government customers typically exercise independent contracting authority, and even offices or divisions within an agency or department may directly, or through a prime contractor, use our services as a separate customer so long as that customer has independent decision-making and contracting authority within its organization. The U.S. Army Tank-Automotive Armament Command (TACOM) contract accounted for 8.5% and 22.0% of our revenues and 7.0% and 15.7% of our operating income for the six months ended June 30, 2014 and 2013, respectively. Revenues from the U.S. government under prime contracts and subcontracts were approximately 98.9% and 99.0% of our revenues for the six months ended June 30, 2014 and 2013, respectively. We treat sales to U.S. government customers as sales within the United States regardless of where the services are performed.

Each investee has a 50% ownership interest in FMLS. Because we have the ability to exercise significant influence over, but do not control, FMLS we determined that the equity method of accounting will be used for our investment. Under the operating agreement, we are required to provide additional financial support for losses incurred by FMLS. We recorded $65 thousand and $0 in equity method losses for the three months ended June 30, 2014 and 2013, respectively. We recorded $122 thousand and $0 in equity method losses for the six months ended June 30, 2014 and 2013, respectively.
