I am not talking of bootleg projects, but a officially sanctioned project with Boeing. no harm in asking. if they refuse, then yes MTA is an option OR we can resurrect the defunct A321 MPA program from EADS and tune it to our needs, MTA -- its fuselage , speed, range is inferior in the bomber role due to its cargo hauler design. bombers need to be fast, long range, low drag, with slim but strong fuselages..all dedicated bombers follow that model including the H-6.
and cargo haulers have very low ground clearance due to gondola outrigger wheels. nothing can be slung below fuselage, so under wings will be only option or the costly and complex rotary bays again suited to slim fuselages only.
in contrast the 737 presents a middle ground and easier conversion opportunity.
P8 has two tandem (inline) pylons below fuselage for harpoons. needs some beefing up there for a single pair of side by side nirbhay. I am deleting the rear pylon to avoid ground scraping issue with a bigger missile in nose flared up landings.
ER tanks are already in the P8 I believe. we can delete the LRMP seats and add more. mission systems are already ruggedized, EW systems installed, radar is there, so is crew seating and comforts, FCS tuned to bank 45' bank angle vs 28' on civilian model....its ready to roll..and no internal bay needed either...use the sonobuoy bay to launch countermeasures if needed...and maybe the LWT torpedo bay can host another couple petite slim micro-brahmos
far more realistic timeline vs MTA.
