So, why B-1 runs with F-101 engine instead of PW-220 or something like that ? Will the new B-21 runs with F-135 ? or can F-135 core directly transplanted to B-21 engine ?

Is it so hard to understand that these fighters and bombers have different needs for their respective engine.

Except that for whatever Russian, you will have to deal with Rosoboroneksport. and later Rosoboroneksport will appoint local country agent. Which in our earlier Flanker, was handled by Trimarga co.

There is no real “G2G” deal in here.

Im disappointed that PAKFA havent opened her internal bay

315 ft long and 42 ft diam. with larger horsepower than 45000 Shp Seawolf. it would be about 8200 metric-ton class surface. assuming Reserve of Buoyancy of 10% typical US Sub, submerged displacement would be 9020 ton. Assuming half volume of it (like 4000 cubic meters) allocated for propulsion. Seems like 50000-60000 Shp plant is possible, and this could drive the boat with speed about 40 Knot at 60000 Shp.

Given the emphasize of high speed, apparently this kinda mimic Soviet deployment of P-705 Lyra (Alfa class). Cruising at such high speed tho, expect cavitation noise to be dominant.

you’re welcome.

It always be good to include means to allow readers to use data or diagram you provided to make their own calculations.

i guess.. we won’t see the 1.4 m Zaslon M aperture on BM-2 eh ?

Im curious if the NK missile have terminal seeker.

Anyway for sake of it.. i brew another excel spreadsheet, based on Fleeman’s tactical missile design book. It’s to estimate accuracy of a missile with mid course update. I tailored itu for ballistic missile use.

Very simple, and well clearly shows that some kind of mid course update is needed for smaller acquisition box for the missile’s terminal seeker. smaller acquisition box means smaller seeker as it requires less power, lesser antenna movement, and perhaps lesser processing as the seeker only need to find smaller area.

I made it for DF-21 case but. clearly it would be applicable for NK case.
