  From a Bell/Boeing sheet on the "SV-22 as subkiller":

  "...the V-22 Osprey could make it possible to detect and defeat hostile
submarines hundreds of miles from CV and protect non-CV assets such as
AMPHIIBs, URGs, SAGs, BBBGs, and CONVOYs.
   ...Osprey is also shipboard compatible.  It will base aboard aviation
ships but will be capable of staging from the flight decks of an additional
80 to 90 Navy vessels, including all DD-963-class destroyers and CG-47
cruisers.  The V-22 is capable of all-weather instrument flight, day or
night -- even in moderate icing conditions.
   In an antisubmarine warfare role, the SV-22 would be capable of hovering
to deploy and recover sensors and/or employ an advanced active sonar as well
as passive sono-buoy tactics.  Its avionics suite will be based on the Update
IV package currently being developed by Boeing for the P-3 Orion.  Improved
sensors, including advanced radar and FLIR, will enhance the fire-control
systems.  The Osprey's weapon mix can include sub-killing torpedoes as well
as antiship and antiaircraft missiles."

  It goes on to give some dimensions and performance figures:

  Length, aircraft mode:     57.9 ft
  Span, rotors turning:      84.6 ft
  Length, stowed:            62.6 ft
  Width, stowed:	     18.4 ft
  Cruise, normal:            240 kn 
  Dash speed:                275 kn
  Max mission radius:        660 nmi
  Max mission endurance:     3.9 hrs
   
The last two figures are footnoted to the effect that they hold for vertical
take off, with an 11 knot wind over the deck and 150 nmi forward staging. The
last figure is also footnoted as being 25% hover on station.
  I don't claim to know the least bit about ASW, I'm just relaying some of the
information I have on the aircraft.  Make of it what you will.
