Breda Folgore
The Folgore (''Thunderbolt'') is an Italian 80 mm recoilless anti-tank weapon developed and manufactured by Breda Meccanica Bresciana. It weighs 18.9 kilograms (with bipod) and 25.6 kilograms (with tripod). Development of the Folgore started in 1974 and it was adopted by the Italian Army in 1986. Over 800 Folgores had been produced by 2001.〔(forecastinternational.com )〕
==Description==
The Folgore's launcher is a recoilless rifle that fires a ''boost-after-launch'' rocket projectile. It consists of a long, reusable launch tube constructed of high strength nickel-cobalt-steel. The use of nickel-cobalt-steel not only keeps the weight at a reasonable level, but also enables the firing of projectiles at a much higher velocity, than other weapons previously in its class. To load the Folgore, the nozzle clamp has to be released and tilted to the side to insert the ammunition. The cartridge case is perforated with holes along its sides to allow gases to escape to the back and out of the nozzle on firing to achieve a recoilless effect. One kilogram of propellant in the cartridge case is used to fire the projectile. After the projectile exits the muzzle, six fins snap into place. The fins are canted slightly to impart spin. After the projectile has coasted a safe distance a rocket motor ignites, boosting the projectile from 385 m/s to 500 m/s, giving the projectile an almost flat trajectory to 500 m.〔Eric Laurie "FOLGORE - An Advance in unguided anti-tank weapons" page 56-57 Asian Journal No. 2/1980〕〔There are many defence commentators in Italy who believe the Folgore was a political works project and a re-invention of the wheel〕
