The Space and Missile Systems Center at Los Angeles AFB, Calif., has issued a final request for proposals for the Transformational Satellite Communications System space segment. The contract could be worth up to $15 billion. Teams led by Boeing and Lockheed Martin have been vying for TSAT, both successfully completing system design reviews earlier this year. The Air Force expects to launch the first TSAT spacecraft in 2016. Congress withheld some TSAT funding last year, but they seem inclined this year to support the Administration request.
Denys Overholser, the Lockheed Martin engineer whose insights on the mathematics of radar cross section led directly to the first operational stealth attack airplane and permanently reshaped combat aircraft design and tactics, died April 28 at the age of 86.
