A lot of engine development programs struggle with attenuating instabilities, most notably the Saturn V's @AerojetRdyne F1. After destroying many chambers in testing, they launched a program called Project First to stabilize the engine's transient & steady-state

RS-68A, improved RS-68, is used on the cores of Delta IV Heavy. It runs on LH2 and LOX. RS-68A is the most powerful hydrogen-fueled engine with thrust of 3,136kN and ISP of 362s (both on sea level). It's 2.4m in diameter and 5.2m high. It was first used in 2012.

A closer perspective of this morning's Delta IV Heavy launch for the NRO. Each Delta IV Common Booster Core (CBC) is equipped with an @AerojetRdyne RS-68A engine, providing 9300kN of combined thrust on the first stage of the rocket! Tory Bruno

Qualification testing for @AerojetRdyne's AEPS 12 kW thruster has begun:
nasa.gov/feature/glenn/…
125 W/kg with PPU, 60% efficiency, up to 2800s Isp.

There will be three of them aboard the Lunar Gateway by 2025, alongside Maxar-Busek 6 kW thrusters.

Hey Northrop Grumman your website says you made the worlds largest SRB, but didn’t @AerojetRdyne make the AJ-260? I thought that was the biggest SRB ever?
Granted it never flew anywhere
