Their Titan I missile, developed as an Atlas backup, had a conventional two stage design. Engines. The booster engine consisted of two large thrust chambers. On the Atlas A/B/C, one turbopump assembly powered both booster engines. On the Atlas D, the booster engines had separate pump assemblies.

The X-11 was originally designed to fly with just one booster engine. The Atlas A operated with two North American booster engines, each of which provided a thrust of 120,000 pounds at liftoff. It also employed two vernier engines, located on opposite sides of the missile above the booster engine fairing.

Jan 1, 2021 · Atlas missiles used five Rocketdyne engines; two LR89 boosters, a single LR105 sustainer engine, and two LR101 vernier engines that provided roll control and fine targeting.
Atlas-A missile (PGM-16A) Atlas-A rockets flew sub-orbital test flights. The missions did not fly with a sustainer engine. Only the two booster engines were included. The first flight, launched on 11 June 1957, was a failure. A total of eight Atlas-A rockets were launched in 1957 and 1958.
The propulsion system used on the initial Atlas As was an early version of the Rocketdyne MA-1 engines with conical thrust chambers that produced a mere 135,000 pounds of thrust, compared with the 360,000 pounds of the fully operational Atlas D.
