DRS TECHNOLOGIES PRICES OFFERING OF $300 MILLION OF

CONVERTIBLE SENIOR NOTES

PARSIPPANY, N.J., January 30 — DRS Technologies, Inc. (NYSE: DRS) announced today that it has priced a private placement of $300 million aggregate principal amount of convertible senior notes due 2026. DRS also has granted to the initial purchasers of these notes a 13-day option to purchase up to an additional $45 million principal amount of the notes. The sale of the convertible notes is expected to close on January 31, 2006, subject to customary closing conditions.

DRS intends to use the net proceeds from the offering, together with other available funds, to finance its previously announced acquisition of Engineered Support Systems, Inc. (NASDAQ: EASI), to repay certain of Engineered Support Systems’ outstanding indebtedness, and to pay related fees and expenses.

DRS will pay interest on the convertible notes at an annual rate equal to 2.0 percent until maturity on February 1, 2026, subject to earlier repurchase, redemption or conversion. The notes will have an initial conversion rate of 16.7504 shares of DRS’s common stock per $1,000 principal amount of convertible notes, representing an initial conversion price of $59.70, which is a premium of 20 percent over the closing common stock price of $49.75 per share on January 27, 2006.

DRS will settle each $1,000 principal amount of convertible notes surrendered for conversion by delivering cash in an amount equal to the lesser of the principal amount of convertible notes surrendered for conversion or the conversion value; if the conversion value is greater than the principal amount, DRS will deliver an amount of shares equal to the sum of the daily share amounts for each trading day during the applicable conversion period.

DRS may redeem all or some of the convertible notes for cash at any time after February 1, 2009, subject to certain conditions. The holders of the convertible notes may require DRS to repurchase the convertible notes for cash on February 1, 2011, 2016 and 2021 at the par amount plus accrued interest, if any.
