- --------------------------------------------------------------------------------

              As I write to you in early December, the equity markets have
              rallied. Several factors are responsible. First, the presidential
              election is over. Investors are relieved that the uncertainty has
              ended, the results are not in dispute, and no terrorist attack
              occurred on U.S. soil. In addition, the U.S. economy is on sound
              footing. The annual gross domestic product (GDP) - the total value
              of all the goods and services produced in the country - is
              expected to be up around 4%, on an inflation-adjusted basis, in
              2004 and a moderate yet healthy 3.5% in 2005. In most of America,
              the housing market remains strong. Inflation is also under
              control, which has kept long-term interest rates in check.

              The Federal Reserve Board (the Fed) is expected to continue
              raising short-term interest rates at a measured pace. In fact,
              the Fed has announced its intention to move toward a more
              "neutral" interest-rate position, which should put short-term
              rates above 3% sometime in 2005. This is good news for money
              market investors, because as your yields rise, you will be paid
              more on your cash positions. At the same time, however, interest
              rates on credit-card debt will also increase. In the months
              ahead, we expect to see a narrowing of the yield relationship
              between bonds of different maturities. In other words, the yield
              curve will "flatten." We do not expect a major increase in
              long-term interest rates, which the bond market, not the Fed,
              controls.


                                                                               3

 . . . C O N T I N U E D
========================--------------------------------------------------------

              In 2005, the primary drivers of stock market performance will be
              the growth in corporate earnings, the valuation of those earnings,
              Fed policy changes, and the level of long-term interest rates.
              Corporate earnings are expected to improve by about 7%. The dollar
              is likely to remain weak relative to foreign currencies, making
              American products more affordable around the world and helping the
              U.S. GDP. But because foreign governments finance the federal
              budget deficit, the bond market may push up long-term rates to
              make U.S. securities more attractive to foreign investors.

              Whatever lies ahead, we remain committed to delivering quality
              USAA service and providing you with a range of resources,
              including our market-tested portfolio management team and no-load
              mutual funds without excessive fees. On behalf of everyone at

              November 30, 2004.

WHAT WAS THE MARKET ENVIRONMENT DURING THE PERIOD?

              Slower economic growth tends to create more favorable conditions
              for bonds. Over the six-month period, the bond market focused on
              employment as the key measure of the economy. When data came out
              showing a weak job market, the bond market rallied. When there was
              a strong jobs report, the market sold off.

              Of course, the market also had to deal with the Federal Reserve
              Board (the Fed), which in June 2004 began a tightening regimen
              that took short-term rates from 1% to 2% in four moves of 0.25%
              each. The net effect was that short-term rates doubled while
              intermediate- and long-term rates fell.

HOW DID MORTGAGE-BACKED SECURITIES PERFORM?

              Mortgage-backed securities tend to perform well in periods of
              slightly rising or stable interest rates, principally because they
              have higher yields and relatively short durations (a measure of
              interest-rate sensitivity). Also, now that the period of plunging
              interest rates has ended, so has the wave of mortgage pre-payments
              that previously had such a negative impact on mortgage-backed


                                                                              11

              securities. In this environment, mortgage-backed securities
              performed well.

HOW DID YOU MANAGE THE FUND?

              We continued to be concerned about the possibility of rising
              interest rates, so we kept the Fund's duration relatively short.
              This slightly hindered performance, since longer-term bonds
              outperformed shorter-term bonds. We continued to invest in
              slightly higher-coupon mortgages, since they should suffer less of
              a price decline should rates rise. And finally, we eliminated our
              position in Treasury inflation-protected securities (TIPS), taking
              profits when we thought they had fully priced in inflation
              expectations.

HOW DOES A GNMA DIFFER FROM A FANNIE MAE OR FREDDIE MAC?

              GNMAs are backed by the full faith and credit of the U.S.
              government, just like Treasury securities. Fannie Mae and

                         COMMENTARY on the Fund

              Freddie Mac are government-sponsored enterprises (GSEs), which are
              not backed by the full faith and credit of the U.S. government,
              but supported only by the issuing entity.

WHAT'S YOUR MARKET OUTLOOK?

              Although employment reports have been inconsistent, we see signs
              of continued economic growth, and expect the Fed to continue
              raising short-term interest rates. Even as short-term rates rise,
              however, the difference between long-term and short-term rates
              seems to be enough to allow longer-term rates to remain relatively
              stable, or to rise only slightly. This should be a good
              environment for GNMAs. Rates are now at relatively more attractive
              levels than they have been in the last two years, and we are
              finding many opportunities to make investments.

              If we've learned anything in 2004, it's the importance of staying
              diversified. We thank you for the opportunity and privilege of
              serving you.

USAA GNMA TRUST
NOVEMBER 30, 2004 (UNAUDITED)

(1) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
- --------------------------------------------------------------------------------

         USAA INVESTMENT TRUST (the Trust), registered under the Investment
         Company Act of 1940, as amended, is a diversified, open-end management
         investment company organized as a Massachusetts business trust
         consisting of nine separate funds. The information presented in this
         semiannual report pertains only to the USAA GNMA Trust (the Fund). The
         Fund's investment objective is to provide a high level of current
         income consistent with preservation of principal.

           A. SECURITY VALUATION - The value of each security is determined (as
              of the close of trading on the New York Stock Exchange on each
              business day the exchange is open) as set forth below:

              1. Debt securities are valued each business day by a pricing
                 service (the Service) approved by the Trust's Board of
                 Trustees. The Service uses the mean between quoted bid and
                 asked prices or the last sales price to price securities when,
                 in the Service's judgment, these prices are readily available
                 and are representative of the securities' market values. For
                 many securities, such prices are not readily available. The
                 Service generally prices these securities based on methods
                 that include consideration of yields or prices of securities
                 of comparable quality, coupon, maturity, and type; indications
                 as to values from dealers in securities; and general market
                 conditions.

              2. Securities purchased with original maturities of 60 days or
                 less are stated at amortized cost, which approximates market
                 value. Repurchase agreements are valued at cost.

              3. Securities for which market quotations are not readily
                 available or are considered unreliable, or whose values have
                 been materially affected by events occurring after the close of
                 their primary markets but before the pricing of the Fund, are
                 valued in good faith at fair value, using methods determined by

USAA GNMA TRUST
NOVEMBER 30, 2004 (UNAUDITED)

                 USAA Investment Management Company (the Manager), an affiliate
                 of the Fund, under valuation procedures approved by the
                 Trust's Board of Trustees. Valuing securities at fair value is
                 intended to cause the Fund's net asset value (NAV) to be more
                 reliable than it otherwise would be.

           B. FEDERAL TAXES - The Fund's policy is to comply with the
              requirements of the Internal Revenue Code applicable to regulated
              investment companies and to distribute substantially all of its
              income to its shareholders. Therefore, no federal income tax
              provision is required.

           C. INVESTMENTS IN SECURITIES - Security transactions are accounted
              for on the date the securities are purchased or sold (trade date).
              Gain or loss from sales of investment securities is computed on
              the identified cost basis. Interest income is recorded on the
              accrual basis. Discounts and premiums are amortized over the life
              of the respective securities, using the effective yield method for
              long-term securities and the straight-line method for short-term
              securities.

           D. REPURCHASE AGREEMENTS - The Fund may enter into repurchase
              agreements with commercial banks or recognized security dealers.
              These agreements are collateralized by obligations issued or
              guaranteed as to both principal and interest by the U.S.
              government, its agencies, or its instrumentalities. Government-
              sponsored enterprises (GSEs), such as Federal National Mortgage
              Association (Fannie Mae) and Federal Home Loan Mortgage
              Corporation (Freddie Mac), are supported only by the credit of
              the issuing U.S. government agency, and are neither issued nor
              guaranteed by the U.S. government. Obligations pledged as
              collateral are required to maintain a value equal to or in excess
              of the repurchase agreement price plus accrued interest and are
              held by the Fund, either through its regular custodian or through
              a special "tri-party" custodian that maintains separate accounts
              for both the Fund and its counterparty, until maturity of the


                                                                              23

              repurchase agreement. The Fund's Manager monitors the
              creditworthiness of sellers with which the Fund may enter into
              repurchase agreements.

           E. SECURITIES PURCHASED ON A WHEN-ISSUED BASIS - Delivery and payment
              for securities that have been purchased by the Fund on a when-
              issued basis can take place a month or more after the trade date.
              During the period prior to settlement, these securities do not
              earn interest, are subject to market fluctuation, and may
              increase or decrease in value prior to their delivery. The Fund
              maintains segregated assets with a market value equal to or
              greater than the amount of its purchase commitments. The purchase
              of securities on a when-issued basis may increase the volatility
              of the Fund's NAV to the extent that the Fund makes such
              purchases while remaining substantially fully invested. The Fund
              had no when-issued commitments as of November 30, 2004.

           F. EXPENSES PAID INDIRECTLY - Through arrangements with the Fund's
              custodian and other banks utilized by the Fund for cash
              management purposes, realized credits, if any, generated from
              cash balances in the Fund's bank accounts are used to reduce the
              Fund's expenses. For the six-month period ended November 30,
              2004, these custodian and other bank credits reduced the Fund's
              expenses by $1,000.

           G. INDEMNIFICATIONS - Under the Trust's organizational documents, its
              officers and trustees are indemnified against certain liability
              arising out of the performance of their duties to the Trust. In
              addition, in the normal course of business the Trust enters into
              contracts that contain a variety of representations and
              warranties that provide general indemnifications. The Trust's
              maximum exposure under these arrangements is unknown, as this
              would involve future claims that may be made against the Trust
              that have not yet occurred. However, the Trust expects the risk
              of loss to be remote.

           H. USE OF ESTIMATES - The preparation of financial statements in
              conformity with U.S. generally accepted accounting principles
              requires management to make estimates and assumptions that may
              affect the reported amounts in the financial statements.

(2) LINES OF CREDIT
- --------------------------------------------------------------------------------

         The Fund participates with other USAA funds in two joint, short-term,
         revolving, committed loan agreements totaling $500 million: $400
         million with USAA Capital Corporation (CAPCO), an affiliate of the
         Manager, and $100 million with Bank of America and State Street Bank
         and Trust Company (State Street), under which Bank of America and State
         Street have each committed $50 million. The purpose of the agreements
         is to meet temporary or emergency cash needs, including redemption
         requests that might otherwise require the untimely disposition of
         securities.

         Subject to availability under its agreement with CAPCO, the Fund may
         borrow from CAPCO an amount up to 5% of the Fund's total assets at a
         rate per annum equal to the rate at which CAPCO obtains funding in the
         capital markets, with no markup. Subject to availability under its
         agreement with Bank of America and State Street, the Fund may borrow
         from Bank of America and State Street, at the federal funds rate plus a
         0.50% markup, an amount which, when added to outstanding borrowings
         under the CAPCO agreement, does not exceed 25% of the Fund's total
         assets.

         The USAA funds that are party to the loan agreements are assessed
         facility fees in aggregate by Bank of America and State Street in an
         annual amount equal to 0.09% of the $100 million loan agreement,
         whether used or not, and by CAPCO based on the funds' assessed
         proportionate share of CAPCO's operating expenses related to obtaining
         and maintaining CAPCO's funding programs in total (in no event to
         exceed 0.09% annually of the $400 million loan agreement). The facility


                                                                              25

NOVEMBER 30, 2004 (UNAUDITED)

         fees are allocated among the funds based on their respective average
         net assets for the period. For the six-month period ended November 30,
         2004, the Fund paid CAPCO facility fees of $3,000. The Fund had no
         borrowings under either of these agreements during the six-month period
         ended November 30, 2004.

         On November 17, 2004, the Trust's Board of Trustees approved, effective
         January 6, 2005, the termination of the $100 million line of credit
         with Bank of America and State Street and the renewal of the line of
         credit with CAPCO at a reduced amount of $300 million.

(3) DISTRIBUTIONS
- --------------------------------------------------------------------------------

         The tax basis of distributions and accumulated undistributed net
         investment income will be determined based upon the Fund's tax year-end
         of May 31, 2005, in accordance with applicable tax law.

         Net investment income is accrued daily as dividends and distributed to
         shareholders monthly. Distributions of realized gains from security
         transactions not offset by capital losses are made annually in the
         succeeding fiscal year or as otherwise required to avoid the payment of
         federal taxes. At May 31, 2004, the Fund had capital loss carryovers of
         $36,018,000 for federal income tax purposes, which if not offset by
         subsequent capital gains, will expire between 2005 and 2012, as shown
         below. It is unlikely that the Trust's Board of Trustees will authorize
         a distribution of capital gains realized in the future until the
         capital loss carryovers have been utilized or expire.

(4) INVESTMENT TRANSACTIONS
- --------------------------------------------------------------------------------

         Cost of purchases and proceeds from sales/maturities of securities,
         excluding short-term securities, for the six-month period ended
         November 30, 2004, were $95,322,000 and $114,221,000, respectively.

         As of November 30, 2004, the cost of securities, for federal income
         tax purposes, was approximately the same as that reported in the
         financial statements.

         Gross unrealized appreciation and depreciation of investments as of
         November 30, 2004, were $8,995,000 and $1,296,000, respectively,
         resulting in net unrealized appreciation of $7,699,000.

(5) LENDING OF PORTFOLIO SECURITIES
- --------------------------------------------------------------------------------

         The Fund, through its securities-lending agent, Metropolitan West
         Securities LLC (MetWest), may lend its securities to qualified
         financial institutions, such as certain broker-dealers, to earn
         additional income. The borrowers are required to secure their loans
         continuously with cash collateral in an amount at least equal to the
         fair value of the securities loaned, initially in an amount at least
         equal to 102% of the fair value of domestic securities loaned and 105%
         of the fair value of international securities loaned. Cash collateral
         is invested in high-quality short-term investments. The Fund and
         MetWest retain 80% and 20%, respectively, of the income earned from the
         investment of cash received as collateral. MetWest receives no other
         fees from the Fund for its services as securities-lending agent. Risks
         to the Fund in securities-lending transactions are that the borrower
         may not provide additional collateral when required or return the
         securities when due, and that the value of the short-term investments
         will be less than the amount of cash collateral required to be returned
         to the borrower. The Fund had no securities-lending transactions during
         the six-month period ended November 30, 2004.


                                                                              27

(6) TRANSACTIONS WITH MANAGER
- --------------------------------------------------------------------------------

           A. MANAGEMENT FEES - The Manager carries out the Fund's investment
              policies and manages the Fund's portfolio. The investment
              management fee for the Fund is composed of a base fee and a
              performance adjustment that increases or decreases the base fee
              depending upon the performance of the Fund relative to the
              performance of the Lipper GNMA Funds Index, which tracks the total
              return performance of the 10 largest funds in the Lipper GNMA
              Funds category. The Fund's base fee is accrued daily and paid
              monthly at an annualized rate of 0.125% of its average net assets.

              The performance adjustment is calculated monthly by comparing the
              Fund's performance to that of the Lipper index over the
              performance period. The performance period for the Fund consists
              of the current month plus the previous 35 months.

              The annual performance adjustment rate is multiplied by the
              average net assets of the Fund over the entire performance period,
              which is then multiplied by a fraction, the numerator of which is
              the number of days in the month and the denominator of which is
              365 (366 in leap years). The resulting amount is then added to (in
              the case of overperformance) or subtracted from (in the case of
              underperformance) the base fee, as referenced in the following
              chart:



OVER/UNDER PERFORMANCE                    ANNUAL ADJUSTMENT RATE
RELATIVE TO INDEX(1)                      AS A % OF THE FUND'S AVERAGE NET ASSETS

               EXAMPLE

USAA GNMA TRUST
NOVEMBER 30, 2004 (UNAUDITED)

EXAMPLE
- --------------------------------------------------------------------------------

         As a shareholder of the Fund, you incur two types of costs: direct
         costs, such as wire fees, redemption fees, and low balance fees; and
         indirect costs, including management fees, transfer agency fees, and
         other Fund operating expenses. This Example is intended to help you
         understand your indirect costs, also referred to as "ongoing costs,"
         (in dollars) of investing in the Fund and to compare these costs with
         the ongoing costs of investing in other mutual funds.

         The example is based on an investment of $1,000 invested at the
         beginning of the period and held for the entire six-month period of
         June 1, 2004, through November 30, 2004.

ACTUAL EXPENSES
- --------------------------------------------------------------------------------

         The first line of the table on the next page provides information about
         actual account values and actual expenses. You may use the information
         in this line, together with the amount you invested at the beginning of
         the period, to estimate the expenses that you paid over the period.
         Simply divide your account value by $1,000 (for example, an $8,600
         account value divided by $1,000 = 8.6), then multiply the result by the
         number in the first line under the heading "Expenses Paid During
         Period" to estimate the expenses you paid on your account during this
         period.

HYPOTHETICAL EXAMPLE FOR COMPARISON PURPOSES
- --------------------------------------------------------------------------------

         The second line of the table provides information about hypothetical
         account values and hypothetical expenses based on the Fund's actual
         expense ratio and an assumed rate of return of 5% per year before
         expenses, which is not the Fund's actual return. The hypothetical
         account values and expenses may not be used to estimate the actual
         ending account balance or expenses you paid for the period. You may


                                                                              31

         use this information to compare the ongoing costs of investing in the
         Fund and other funds. To do so, compare this 5% hypothetical example
         with the 5% hypothetical examples that appear in the shareholder
         reports of other funds.

         Please note that the expenses shown in the table are meant to highlight
         your ongoing costs only and do not reflect any direct costs, such as
         wire fees, redemption fees, or low balance fees. Therefore, the second
         line of the table is useful in comparing ongoing costs only, and will
         not help you determine the relative total costs of owning different
         funds. In addition, if these direct costs were included, your costs
         would have been higher.

        *Expenses are equal to the Fund's annualized expense ratio of 0.48%,
         which is net of any expenses paid indirectly, multiplied by the average
         account value over the period, multiplied by 183 days/365 days (to
         reflect the one-half year period). The Fund's ending account value on
         the first line in the table is based on its actual total return of
         3.33% for the six-month period of June 1, 2004, through November 30,
         2004.

STREAMLINED. WE DEVELOP MAILING LISTS USING CRITERIA SUCH AS ADDRESS, MEMBER
NUMBER, AND SURNAME TO SEND ONE REPORT TO EACH HOUSEHOLD INSTEAD OF SENDING A
REPORT TO EVERY REGISTERED OWNER. THIS PRACTICE IS DESIGNED TO REDUCE DUPLICATE
COPIES AND SAVE PAPER AND POSTAGE COSTS TO THE FUND. IF YOU PREFER NOT TO
PARTICIPATE IN STREAMLINING AND WOULD LIKE TO CONTINUE RECEIVING ONE REPORT PER
REGISTERED ACCOUNT OWNER, PLEASE CALL US AND WE WILL BEGIN YOUR INDIVIDUAL
DELIVERY WITHIN 30 DAYS OF YOUR REQUEST.

ITEM 10.  CONTROLS AND PROCEDURES

The  principal  executive  officer  and  principal  financial  officer  of  USAA
Investment Trust (Trust) have concluded that the Trust's disclosure controls and
procedures are sufficient to ensure that information required to be disclosed by
the Trust in this Form N-CSR was recorded,  processed,  summarized  and reported
within the time periods  specified in the Securities  and Exchange  Commission's
rules and forms,  based upon such  officers'  evaluation  of these  controls and
procedures as of a date within 90 days of the filing date of the report.

In October  2004,  certain  changes were made to the policies and  procedures to
address the reporting of audit and non-audit  fees required in annual reports on
Form N-CSR. None of these changes are relevant to this semi-annual report.

There  were  no  significant  changes  or  corrective  actions  with  regard  to
significant deficiencies or material weaknesses in the Trust's internal controls
or in other  factors  that  could  significantly  affect  the  Trust's  internal
controls subsequent to the date of their evaluation.
