NATO Frigates (continued from page 32) armament, with a 4 5-in. gun for- ward and two 30-mm twin-mounts; even the Sea Wolf system will be modified to improve its anti-mis- sile capabilities. All the Type 22 frigates are capable of carrying two Sea Lynx helicopters armed for antisubmarine or antiship operations.

The electronics of this class are among the most sophisticated, particularly command, control and information systems, which can coordinate important air-naval op- erations. Sensors are from Mar- coni, Kelvin-Hughes and Plessay.

The propulsion plant is a COGOG (combined gas or gas) installation with two Rolls Royce Olympus gas turbines with a total of 56,000 bhp and two Rolls Royce Tyne gas tur- bines of 8,500 bhp total providing a maximum speed of 30 knots and a cruising speed of 18 knots with an endurance of 4,500 miles.

Groves, Texas 77619 (409) 962-8549 Telex: SETCO PTNS 77-9337 the Mediterranean theater, planned her new frigates according to the

NATO Project Group concept but with specific technical and operat- ing requirements to meet the in- creasing presence of the Soviet fleet and other potentially hostile navies. The principal mission of the Italian Navy is, together with the U.S. Navy's Sixth Fleet, to provide defense to the convoys from Gibraltar to friendly ports and to prevent operations by en- emy naval forces. A high-intensity threat level characterizes the

Mediterranean situation, and the

Italian Navy developed an ad- vanced multi-role frigate class with powerful and well-balanced arma- ment but a limited displacement.

Five of the eight 3,000-ton

Maestrale Class frigates are al- ready in service. Together with four Lupo Class 2,500-ton frigates, they represent the modern nucleus of the Marina Militare Italiana.

The Maestrale vessels were con- structed by the C.N.R. shipyard in

Riva Trigoso, with extensive utili- zation of prefabricated modular elements.

The design employs, as much as possible, propulsion system, equip- ment, weapons systems and un- doubtedly the experience achieved with the 18 Lupo Class frigates that were built, 14 of which were exported to Peru, Venezuela and

Iraq. The Maestrale Class has been duly adapted to the specific tasks required, particularly all the pre- cautions suggested by up-to-date technology and rules aimed at re- ducing noise levels in order to op- timize antisubmarine charac- teristics.

The armament includes four

OTOMAT surface-to-surface mis- sile launchers, an 8-cell Aspide (Selinia) surface-to-air missile launcher, a 127-mm OTO Melera gun, two DARDO systems with two twin 40-mm BREDA turrets, two SCLAR 105-mm rocket and flare launchers, and two triple tor- pedo tubes.

To carry out antisubmarine op- erations, considered the unit's main task, each Maestrale is equipped with two AB 212 helicopters, and

Raytheon variable-depth sonar aft.

Other sensors and electronics in- clude Selenia radars, Elsag fire control system, Elettronica ECM/

ECCM, Elmer telecommunica- tions, etc. A Selenia IPN 10 pro- vides an advanced and integrated command and control systems.

The propulsion plant is a

CODOG configuration employing two Fiat/General Electric LM 2500 gas turbines with 50,000 total bhp and two GMT diesel engines with 11,000 total bhp. Controls of main engines and electric power plant are fully automated. Maximum speed is 33 knots; cruising speed is 21 knots with a range of 6,000 miles.
