       INFORMATION STATEMENT PURSUANT TO SECTION 14(F) OF THE SECURITIES
                EXCHANGE ACT OF 1934 AND RULE 14F-1 THEREUNDER

     This Information Statement is being mailed on or about March 5, 1999 as
part of the Solicitation/Recommendation Statement on Schedule 14D-9 (the
"Schedule 14D-9") of Aydin Corporation, a Delaware Corporation (the "Company"),
to the holders of record of shares of common stock, par value $1.00 per share,
of the Company (the "Shares"). You are receiving this Information Statement in
connection with the possible election of persons designated by L-3
Communications Corporation, a Delaware corporation ("Parent"), to a majority of
the seats on the Board of Directors of the Company (the "Board" or "Board of
Directors").

     Pursuant to an Agreement and Plan of Merger, dated as of March 1, 1999, by
and among Parent, Angel Acquisition Corp., a Delaware corporation and a wholly
owned subsidiary of L-3 ("Purchaser"), and the Company, Purchaser has commenced
a tender offer (the "Offer") for all of the issued and outstanding Shares at a
price of $13.50 per Share, net to the seller in cash, and following
consummation of the Offer, Purchaser will be merged with and into the Company
(the "Merger"), with the Company surviving as a wholly owned subsidiary of L-3.
 

     The Merger Agreement provides that, promptly after the purchase of and
payment for a majority of the outstanding Shares pursuant to the Offer, Parent
will be entitled to designate such number of directors as will give Parent
representation on the Board proportionate to its ownership interest in the
Shares, rounded up to the next whole number. The Merger Agreement requires the
Company to use its best efforts to cause the Parent designees (the "Parent
Designees") to be elected to the Board under the circumstances described
therein. This Information Statement is being mailed to stockholders of the
Company pursuant to Section 14(f) of the Securities Exchange Act of 1934, as
amended (the "Exchange Act"), and Rule 14f-1 thereunder.

     You are urged to read this Information Statement carefully. You are not,
however, required to take any action. Capitalized terms used herein and not
otherwise defined shall have the meanings set forth in the Schedule 14D-9.

     The information contained in this Information Statement concerning Parent,
Purchaser and the Parent Designees has been furnished to the Company by Parent.
The Company assumes no responsibility for the accuracy or completeness of such
information.


                   CERTAIN INFORMATION REGARDING THE COMPANY


GENERAL

     The Shares are the only class of voting securities of the Company
outstanding. Each issued and outstanding Share is entitled to one vote. As of
March 1, 1999, 5,220,936 Shares were issued and outstanding and 632,550 Shares
were reserved for issuance upon the exercise of certain options and warrants
outstanding.


RIGHT TO DESIGNATE DIRECTORS; THE PARENT DESIGNEES

     The Merger Agreement provides that, subject to compliance with applicable
law, promptly upon the purchase of and payment by Purchaser for Shares pursuant
to the Offer which represent at least a majority of the outstanding Shares (on
a fully diluted basis), Purchaser will be entitled to designate such number of
directors on the Board as is equal to the product of the total number of
directors on the Board (after giving effect to the directors designated by
Purchaser pursuant to this sentence) multiplied by the


                                      A-1


percentage that the aggregate number of Shares beneficially owned by Purchaser,
Parent and any of their affiliates bears to the total number of Shares then
outstanding (such number being the "Board Percentage"). The Company shall, upon
request of Purchaser, cause Purchaser's designees to satisfy the Board
Percentage, including without limitation increasing the size of the Board and
securing resignations of such number of its incumbent directors as is necessary
to enable Parent's Designees to be so elected to the Company Board, and shall
cause Parent's Designees to be so elected. Notwithstanding the foregoing, until
the Effective Time (as defined in the Merger Agreement), the Company shall
retain as members of the Company Board at least two directors who are directors
of the Company on the date hereof (the "Company Designees"); provided, that
subsequent to the purchase of and payment for Shares pursuant to the Offer,
Parent shall always have its designees represent at least a majority of the
entire Company Board. If at any time prior to the Effective Time there are less
than two Company Designees on the Board, Parent, Purchaser and the Company
shall either (i) use their reasonable efforts to appoint successors who are not
affiliated with Parent or Purchaser or (ii) permit the resigning Company
Designee to appoint his or her successors in his or her reasonable discretion.
The Company will use its reasonable best efforts to cause persons designated by
Purchaser to constitute the same percentage as is on the Board of (i) each
Committee of the Board, (ii) each board of directors of each Subsidiary of the
Company and (iii) each committee of each such board, in each case only to the
extent permitted by law. The Company's obligations under the foregoing shall be
subject to Section 14(f) of the Exchange Act and Rule 14f-1 promulgated
thereunder. Parent or Purchaser will supply the Company any information with
respect to either of them and their nominees, officers, directors and
affiliates required by Section 14(f) and Rule 14f-1. Upon receipt of such
information from Parent or Purchaser, the Company shall include in the Schedule
14D-9 (as an annex or otherwise) the information required by Section 14(f) and
Rule 14f-1 as is necessary to enable Parent's Designees to be elected to the
Board.

     Parent has informed the Company that it will choose the Parent Designees
from the directors and executive officers of Parent listed in Schedule I
attached hereto. Parent has advised the Company that each of the initial Parent
Designees has consented to serve on the Board of Directors of the Company and
that, to the best of its knowledge, none of the Parent Designees (i) has a
family relationship with any of the directors or executive officers of the
Company, (ii) beneficially owns any securities (or rights to acquire
securities) of the Company or (iii) has been involved in any transactions, or
has any business relationships with the Company or any of its directors,
executive officers or affiliates, of the type required to be disclosed pursuant
to Rule 14f-1 under the Exchange Act.

                            EXECUTIVE COMPENSATION


     Until November 1998, the Company's executive compensation program was
administered by the Compensation Committee, which was empowered by the Company
Board to review the salaries paid to the Company's officers each year and
recommend to the Company Board any adjustments that it deemed appropriate. The
Compensation Committee also reviewed the nature and scope of the services
rendered each year by the participants in the 1994 Incentive Stock Option Plan
and 1996 Equity Incentive Plan of the Company and the corresponding benefits
derived by the Company from such services. Then, based on the review of
management recommendations, the Compensation Committee awarded bonuses to the
participants. Since November 1998, the entire Board of Directors has assumed
such responsibilities.

EMPLOYMENT CONTRACTS AND TERMINATION OF EMPLOYMENT
AND CHANGE IN CONTROL AGREEMENTS

     The Company entered into an employment agreement with Mr. Bard dated as of
May 6, 1996, pursuant to which Mr. Bard served as Chairman of the Board and
Chief Executive Officer of the Company until his termination on October 19,
1998. The term of the agreement was originally for five years and was
subsequently extended for an additional two years. The Company had the right to
terminate the agreement during its term but only for "Cause" (as defined in the
Agreement), and Mr. Bard had the right to terminate his employment during its
term for "Good Reason" (e.g., a change of his position as Chairman and Chief
Executive Officer) or in the event of a "Change in Control" (e.g., merger,
consolidation, reorganization, sale, lease, exchange or other disposition of
the Company assets or capital stock of more than 50%). The agreement provided
for a base salary of $290,000, which was reviewed annually by the Company
Board.


                                      A-8


     The Company has received notice from Mr. Bard that it is currently in
default under his employment agreement resulting from his termination as
Chairman of the Board and Chief Executive Officer of the Company on October 19,
1998. The Company is currently in discussions with Mr. Bard with respect to its
obligations to him under the agreement. In the event that his agreement was
terminated by the Company other than for "Cause," the Company would be
obligated to pay his base salary for the shorter of three years or until the
initial term of the agreement expires.


     The Company entered into executive retention agreements (collectively, the
"Retention Agreements") with certain key officers of the Company. Except for
Mr. Henderson, the Company has not entered into a Retention Agreement with any
other Named Executive Officer. The Retention Agreements, effective as of
September 16, 1998, provide, among other things, (i) for the payment of a
retention bonus if in the absence of a Change in Status Transaction (as defined
in the Retention Agreements) the executive remains continuously employed by the
Company for a period of one year from the date of the Retention Agreement or
for a period of six months following the date of a Change in Status Transaction
occurring during such one year period and (ii) for the payment of certain
severance benefits if the executive's employment is terminated by the Company
without Cause (as defined in the Retention Agreements) or by the executive for
Good Reason (as defined in the Retention Agreements) within the two year period
following the date of the Retention Agreement. The amount of the retention
bonus payable under the Retention Agreements is equal to twenty-five percent
(25%) of the executive's annual base salary. The severance benefits an
executive will receive under the Retention Agreements include the executive's
full base salary for the one year period subsequent to the date of his
termination, the full exercisability for one year of all options to purchase
shares of the Company's Common Stock granted to the executive, and the
continuance of all life insurance and medical plans until the end of the one
year period subsequent to the date of the executive's termination or, if
sooner, until his commencement of full-time employment with a new employer.

     To the Company's knowledge, based solely on review of the copies of such
