Stock price is thought to be a barometer of future earnings so at least part of Aerojet's future appears to have been answered by the market place.
Here is a rough timeline put together by me
The mission began when Aerojet Rocketdyne’s RS-68A engine ignited to provide more than 705,000 pounds of liftoff thrust that helped boost the Delta IV rocket off the pad. Following the boost phase of the flight, a single RL10B-2 engine ignited to provide 24,750 pounds of thrust to power the upper stage into orbit. Twelve Aerojet Rocketdyne MR-106H monopropellant (hydrazine) thrusters packaged in four modules on the Delta IV upper stage provide roll, pitch and yaw control as well as propellant settling burns.....The GPS III SV02 satellite, built by Lockheed Martin for the Air Force, uses Aerojet Rocketdyne thrusters for orbit maintenance and adjustment, attitude control and end-of-life decommissioning. The spacecraft is equipped with 12 Aerojet Rocketdyne MR-103G thrusters, each generating 0.2 pounds of thrust, and six MR-106L thrusters, each producing 5 pounds of thrust.
The largest U.S. defense contractor Lockheed Martin announced Dec. 20 it has inked a deal to acquire rocket engine and missile manufacturer Aerojet Rocketdyne for $4.4 billion. James Taiclet, Lockheed Martin’s president and CEO, said the acquisition gives the company a larger footprint in space and hypersonic technology.
Well, it seems that the question posed in this thread has finally been answered. Lockheed has agreed to acquire AJR for $4.4 billion. The acquisition is expected to close in the second half of 2021.
