A request for proposals for integrated electronic assemblies (IEA) for the Space Shuttle's solid-rocket boosters had been issued by Marshall Space Flight Center, MSFC announced. The proposals would be for design, development, test and evaluation, fabrication, and assembly of 33 IEAs. The Space Shuttle would carry two refurbishable IEAs, one forward and one aft, to route commands from the Orbiter to the thrust-vector control system to release the nosecap and frustum, jettison the solid-rocket motor nozzle, detach parachutes, and turn on the recovery aids.
