	I missed a few days postings so I appologize if I'm answering a
question that's already been answered.

	A question was asked about anti-air capabilities of submarines.

[stuff deleted about the performance of various missiles]
These weapons [Blowpipe] have been acquired by many armies of the world and 
the British have also adapted it to some of their submarines and surface
ships. [stuff about similar missiles deleted]
	During the war about 100 Blowpipe missiles were fired at enemy aircraft,
downing nine. A British Harrier was also downed by an Argentine Blowpipe. Given
the number of Blowpipes fired, this is a reasonably good success rate. However,
the Blowpipe had several shortcomings which caused this low performance. More
modern weapons of this type have been modified to rectify these deficiencies.
	The Blowpipe is a small (12.7 kilogram) missile in a fiberglass
canister. An aiming unit is clipped to the canister. The missile is 1.39 meters
long, 19.6 centimeters in diameter when in its container, and 26.7 centimeters
in diameter with its wings extended. The Blowpipe, with a range of 6.5
kilometers, is shoulder-fired by a single man at a low-flying aircraft. The
aircraft may be identified by an IFF attatchment on the firing canister. An
explosive charge expels the missile from its container. The exploding debris
is ejected from the rear end of the canister and serves as a hazard to those 
near the blast. When the missile has left the tubeand its sustainer motor
has ignited, the operator, sighting on the missile's tail flares through a
monocular sight, guides the missile with a thumb-operated flight controller.
The millise follows the directions generated by means of radio signals
broadcast to it from a small transmitter is the flight controller unit. The
missile, with a proximity fuse, is designed to explode close to its target
and its two-kilogram warhead does serious damage to the aircraft.
	Since the Blowpipe missile homes on only the aircraft's exhaust, the
thumb control of the missile proved to be a clumsy means of fire control. Heat
flares dropped from aircraft, including helicopters, easily decoyed it. The
very small warhead used in a proximity explosion mode frequently proved less
than lethal to its aircraft target. Because of its mach 1.5 speed, it only
proved adequate for firing at aircraft in the subsonic speed range. The 
target's movement across the operator's line of sight made manual guidance
of the missile virtually impossible. Some of these shortcomings are being
rectified by use of a television vidicom unit, which provides semi-automatic
guidance for the weapon.
	When the Blowpipe is used on a submarine, it is configured in a
battery of six missiles centered around a television vidicom system, which is
mounted inside the bridge on the submarine's sail. For surface ships, a 
battery of two to ten launchers has been developed, also using the television
vidicom system for guiding the missiles. 


	Hope this helps clear up any confusion about the Blowpipe missile
and/or its possible use on submarines.
