Aerojet Rocketdyne

NASA has delayed the planned Feb. 25 full-duration hot fire of the Space Launch System (SLS) core stage due to a faulty valve in the system that supplies liquid oxygen to one of the vehicle’s four Aerojet Rocketdyne RS-25 engines.

NASA has decided to repeat the static test fire of the first Space Launch System (SLS) core stage following an abbreviated burn of the vehicle’s four Aerojet Rocketdyne RS-25 engines two weeks ago.

NASA did not immediately say why the hot fire was cut off about 67 sec. after ignition.

The agreement on the all-cash transaction includes a $5 per share, pre-closing special dividends to Aerojet’s shareholders, reducing the post-dividend value of the deal to $4.6 billion.

Lockheed Martin has won a sixth prime contractor role in a U.S. hypersonic missile program.
