Also learned by researching last night on differences between the -53 models that it looks like the USAF is retiring their MH-53's.
Yes - I do know that they have been looking to retire those MHs for quite some time. NIce avionics - but the ariframes were D models I thought. Quite underpowered according to the guys in Osan that I spoke too. The MVs will be taking on that role I believe.
