At the risk of incurring FH's ire, I'm venturing over from the Mil Aircrew section to post this (I wanted to get it on the record somewhere on the forum, and they said it should go here, which is logical).
The first was a post I made on Key Publishing's Modern Military Aviation discussion board on 28 November 2012:
And the USMC has 11 operational squadrons flying MV-22B/Cs, as well as the MV-22B/CV-22B training squadron (a USMC squadron, but trains the USAF pilots as well)!
As of January 2012, the USMC had 97 MV-22B/Cs on inventory, and the USAF had 13 CV-22Bs in 3 Special Ops squadrons.
So those accidents are spread over a decent number of aircraft.
The production schedule shows 39 MV-22Cs/CV-22Cs are to be delivered to the USMC & USAF this year.
CV-22B Osprey - Standard air force production variant with ramp gun
MV-22B Osprey - Standard naval production variant with ramp gun
CV-22C Osprey - Upgrade program with nose gun pod, avionics upgrade, and countermeasures upgrade for CV-22B
MV-22C Osprey - Upgrade program with nose gun pod, avionics upgrade, and countermeasures upgrade for MV-22B
The MV-22C also features "improved software and cabin temperature controls".
There are only 6 operational and one training CH-46 squadrons left in the USMC.
Note that the "increased armament Osprey" was in development long before the March 2014 incident.
I posted this on the Warships1 discussion board's Aircraft Carriers section on 11 August 2013 in response to discussion of the deployment of USS Boxer LPH-4 with a USMC MV-22 squadron:
USN LHDs have been deploying with MV-22s since October 2007 when they headed to Iraq/Afghanistan aboard USS Wasp (LHD 1).
Boxer's deployment is simply the first aboard a West Coast based LHD.
In Feb. this year MV-22s made their first deployment aboard USS Bonhomme Richard (LHD-6), which is based in Sasebo, Japan.
Also note that the USMC is down to 5 active and 1 training CH-46 squadrons, but are up to 12 active and 1 training MV-22 squadrons... so the lack of CH-46s is no surprise.
And then on 15 December 2013 I posted this on the Warships1 discussion board's Air Forces section in response to discussion of Japan placing the MV-22 in its 5-year Mid-Term Defense Program:
Ummm... the USMC already has transitioned most of its CH-46 squadrons to MV-22s* - so I'm sure Okinawa has already experienced the Osprey (since there are two USMC MV-22 squadrons based on Okinawa at MCAS Futenma)!
*Current list:
CH-46: HMM-268, HMM-364, HMMT-164 (training) (all Camp Pendleton, Ca); HMM-774 (reserve, NS Norfolk, Va).
MV-22: VMM-161, VMM-163, VMM-165, VMM-166, VMM-363 (all MCAS Miramar, Ca); VMM-261, VMM-263, VMM-264, VMM-266, VMM-365, VMMT-204 (training) (all MCAS New River, NC); VMM-262, VMM-265 (both MCAS Futenma, Japan); VMM-764 (Reserve, Edwards AFB, Ca); VMX-2 (test & development, MCAS New River, NC)
CH-46 - 3+1; MV-22 - 12/1/1/1
Changes to the above list are as follows:
HMM-268: In October 2013 the squadron relocated to MCAS Miramar and was assigned to Marine Aircraft Group 16. On April 10th, 2014 the squadron was re-designated as Marine Medium Tiltrotor Squadron 268 (VMM-268).
HMM-774: 10 Feb, 14 -The Marine Medium Helicopter Squadron 774 (HMM-774), stationed out of Norfolk, Va., is currently in the process of retiring their CH-46E Sea Knight transport helicopters, whose service spans 50 years, while transitioning to the V-22 Osprey tilt-rotor aircraft.
HMM-364: Report on HMMT-164's facebook page from 21 July 2014 has HMM-364 turning in two of its aircraft to HMMT-164
without replacement - indicating that the last operational USMC CH-46 squadron has begun the process of transitioning to the MV-22B!
So the standings now look like this:
CH-46: HMM-364 [
in transition], HMMT-164 (training) (both Camp Pendleton, Ca).
MV-22: VMM-161, VMM-163, VMM-165, VMM-166, VMM-268, VMM-363 (all MCAS Miramar, Ca); VMM-261, VMM-263, VMM-264, VMM-266, VMM-365, VMMT-204 (training) (all MCAS New River, NC); VMM-262, VMM-265 (both MCAS Futenma, Japan); VMM-764 (Reserve, Edwards AFB, Ca); HMM-774 (reserve, NS Norfolk, Va)[
in transition]; VMX-2 (test & development, MCAS New River, NC)
CH-46 - 1+1; MV-22 - 13/2/1/1
