B. (U) BRIEF DESCRIPTION OF MISSION REQUIREMENT AND SYSTEM CAPABILITIES:

(U) This project will demonstrate the launch of a guided interceptor (D-2) from a hypervelocity launcher (HVL) with associated fire control to demonstrate the potential of a HVL system as a candidate weapon system for Theater Missile Defense (TMD) in the near term and other longer range applications in the far term. This involves the development of the Gee-hardened D-2 projectile which is a command guided to terminal homing interceptor.

(U) This project is assigned to the Budget Activity and Program Element codes as identified in this descriptive summary in accordance with existing Department of Defense policy. Further justification of the Budget Activity code assigned to each Program Element is contained within the Brief Description of Element section of each Program Element Summary.

C. (U) PROGRAM ACCOMPLISHMENT AND PLANS:

(U) FY 1993 Accomplishments:

o ($8,000K) Demonstrated ability of full scale D2 aeroshell and electronics to survive HVL launch process at 65 KGees

o ($600K) Demonstrated ability of D2 sabot to survive HVL launch process and separate clearly from D2 aeroshell upon exit

o ($400K) Demonstrated ability of interferometric fire control to skin track the D2 interceptor

o ($800K) Operationally verified D2 transmitter and fire control interface

(U) FY 1994 Plans:

o ($700K) Verify performance of D2 transceiver in flight with fire control

o ($3,600K) Assess performance of solid propellant control system in a limited duty cycle mode

o ($300K) Fire control track of maneuvering D2 on the range

(U) FY 1995 Plans:

o Unfunded

(U) Program Plan to Completion: This program is zero funded in FY95 and beyond.

D. (U) WORK PERFORMED BY:

o Martin Marietta - King of Prussia, PA.
