[edit]Development of the OTO Melara 76/62 naval gun series began in 1958. The highly successful 76/62 Compact (over 700 have been produced) appeared in 1967 along with a family of ammunition widely manufactured outside of Italy.

Unquestionably the most successful of the 3"/76mm calibre automatic guns is the OtoBreda 76mm L62, which fires a 76 X 636R cartridge. Originating in the early 1960s, this became immensely popular when a compact version weighing only 7,500kg was introduced in 1969. The rate of fire, initially 60 rpm, was increased to 85 rpm in the Compact and has since been boosted to 120 rpm. For anti-missile purposes a lightweight (5.25kg instead of 6.3kg), high-velocity (1,250 m/s instead of 950 m/s) AMARTOF proximity-fuzed shell is being developed, able to reach a target 3km away in less than three seconds.

Development of the 76/62 super rapid gun mounting began in mid-1980 as an evolution of the 76/62 OTO compact gun mounting. Its main role is anti-missile defense but it is also effective in either anti-aircraft or anti-ship fire. The new mounting maintains the same architecture and aspects and has identical mechanical and electrical interfaces but it can sustain continuous firing of all 80 ready-to-use rounds at more than 120 rounds per minute. In addition it incorporates a local stabilisation system for better aiming and firing accuracy and is provided with a secondary feeding capability that allows a rapid change from anti-air/anti-missile automatic fire to anti-surface and semi-automatic fire, and vice-versa. The electronic portions of the gun have also been updated with safety firing arcs, pointing accuracy check, status display and BITE functions under mini-computer control.

[edit]This is a lot of detailed information page 430 and page 431. It took a JWS 1976-77 and a JWS 1975-76 to flatten it out on the scanner. I need one of those ole Bibles that weight a ton like you see at the front of the churches. <GRIN> Jack --Jackehammond (talk) 06:41, 24 April 2010 (UTC)
