The Bofors 40 mm gun is a famous anti-aircraft autocannon designed by the Swedish firm of Bofors. It was one of the most popular medium-weight anti-aircraft systems during World War II, used by most of the western Allies as well as various other forces. It is often referred to simply as the Bofors gun.

The Precision Guided Munition (PGM) is one of the most potent force multipliers available in the tactical air battle. The high kill probability of modern PGMs ensures that few rounds are required to destroy a target, which reduces the number of sorties to be flown. This in turn translates into a substantial reduction in consumed fuel, flying hours and ultimately attrition of aircraft and aircrew.
While PGMs such as the laser guided bomb and TV guided bomb introduced unprecedented accuracy, the increase in the concentration of hostile defences relative to the number of strike aircraft increased the risks inherent in overflight of the target.
Glidebombs such as the GBU-15 and Walleye I/II family were a partial answer as they allowed the strike aircraft to attack from outside the target''s terminal defences, often fortified with large amounts of visually aimed AAA (guns) which are understandably immune to electronic countermeasures. While the glidebomb packs a lot of punch, its limited range at low altitude and restricted terminal trajectory render its launch platform vulnerable to newer types of SAM. In particular the SA-11 Gadfly and late SA-6 Gainful have a known capability to hit low level targets at ranges of several nautical miles.
The solution to this problem lies in the use of standoff PGMs with sufficient range to allow attacks from below the radar horizon of the target''s area defences.
This strategy has been often used in the design of antishipping missiles and the attacks on the Sheffield and Stark demonstrate its effectiveness. While there are numerous types of standoff anti-shipping missile in use today, few of these have been adapted to the land strike role. The Russian AS-4 Kitchen may have even followed the opposite development path, starting as a strategic land strike missile and eventually shifting to the anti-shipping role.
Key types in the Western inventory are the AGM-109 Tomahawk family (see TE November, 1985) and the AGM-84 Harpoon family.
