F-1A
Exact historical Rocketdyne F-1A uprated liquid rocket engine variant. NASA records F-1A as a proposed F-1 upgrade with two ground-tested engines; the canonical record now carries a direct-derivative-of edge to F-1, while no vehicle installation, actor attribution, or flight claim is asserted.
