Been reading alot about the real life USSR competition to match the USAF's XB-70 for a deep penetration strategic (nuclear) bomber prior to ICBMs taking the stage. It makes alot of sense why the Valkyrie was chosen as basis for the deep (hive) penetration superweapon of MLA, but we don't hear much about other experimental bombers. Anyway, the soviets wanted their own equivalent craft that could perform recon as well as deliver nuclear payloads from high altitudes at super sonic speeds. Tupolev, Myasishchev, , Yakolev and Sukhoi all had interesting concepts, though the soviets ultimately went with the Sukhoi T-4.
What interests me are some of the wacky ideas that didn't make it, that would have some interesting transitions to the MLA world. Myasishchev came up with the M-50, which distpite rumors was fairly conventional. It did however lead to several other productions, prototypes, and concept, specifically the M-60, a nuclear powered nuclear bomber. Tupolev and Myasishchev later joined forces for the Tu-95LAL and Tu-119 nuclear powered crafts.
Considering the short end of the stick that the USSR was left with in MLA, G-elements would obviously be difficult to come by prior to Operation Ouka, but I wouldn't put it past them to try to put together their own XG-70, using what they did have available: nuclear power . Lacking a quantum computer might still be a hinderance, though it appears that Alt III children are capable of some human-powered distributed processing.
If the Soviets were to produce their own HI-MAERF, what craft (assuming they couldn't just reverse engineer the Susano'o) and what gimmicks would they use?
