Derya,

In Response:

a. There are 2 main torpedo tube land attack missiles...The American Tomohawk and the Russian SS-N-27. Both of these are turbojet land attack cruise missiles.

b. Most if not all conventional subs could now be fitted with land attack missiles. There are several torpedo tube sized land attack missiles available at the moment.
Its just a case of buying the missiles and their associated fire control software. While the Americans are unlikely to sell their Tomahawks to all and sundry the Russians have been willing to sell their version with the Kilo class...India is rumoured to have purchased lasn attack cruise missiles with their latest Kilos and have had their older Kilos refitted with them as they are overhauled. It is rumoured that Isreal has modified the Harpoon anti ship missile to carry a nuclear warhead and changed its role to a land attack cruise missile (probably increasing the size of the missile to carry more fuel for greater range). These modified misiles are said to be carried by Isreals new 'Dolphin' class subs.

c. Exocet missiles started in development in 1967, originally as the ship-launched variant MM 38 which entered service in 1975. The air-launched version, AM 39, was developed later starting in 1974 and entering service with the French Navy in 1979. The missile is designed to attack large warships. A block 2 upgrade programme was carried out from the late 1980s until 1993, and introduced an improved digital active radar seeker and upgraded inertial navigation and control electronics.
The Exocet has four clipped delta wings at mid-body and four raked clipped-tip moving delta control fins at the rear. The missile is 4.7 m long, has a body diameter of 350 mm and a wingspan of 1.1 m. The missile weighs 670 kg and has a 165 kg HE shaped charge fragmentation warhead. Guidance in the mid-course phase is inertial, followed by an active radar terminal phase. There is also a radar altimeter to control the sea-skimming trajectory, at around 10.0 m until the terminal phase when, in calm sea conditions, the missile can descend to 3.0 m or so. The solid propellant motor gives Exocet a range of about 50 km, but when released from 10,000 m (32,800 ft) the range achieved was reported to be 70 km.
