1997-068A
This payload was 4.6m in diameter and 12.2m long. The separated Centaur stage is 4.3m diameter and 8.8m long. Launch vehicle was K-20 (A-17)/TC-16. An EHF Milstar polar adjunct package was announced as a secondary payload on an elliptical orbit Titan 4 payload in 1997. The package is derived from the UHF Followon payloads. According to USAF, the NRL's MPTB electronics test bed was launched into a high radiation orbit in 'fall 1997'; I believe this was probably on the K-20 flight.
Publications of space physics data confirm that this satellite is the third in the series of HEO payloads.
