Тема: “expeditionary frigate” F125
Нехилый такой фрегат в 7 тысяч тон немцы строят:
One of the F125’s most challenging demands was the benchmark of a ship that can deploy for up to 2 years away from home ports, while maintaining an average time at sea of more than 5,000 hours per year (almost 60%), including under tropical conditions.
Each frigate has two crews of typically 105 to 120 people, who are changed every four months.
The new ships will use a CODAG (COmbined Diesel-electric And Gas) system that offers more distributed power generation, as well as quieter operation. On each F125 vessel, 4 MTU 20V 4000 M53B diesel engines and generators offer 3,015kW /4,100 hp each, producing a total of 12,060kW/ 16,400 hp for the ship’s on-board power supply system, and/or provide diesel-electric propulsion power for cruising speeds of up to 20 knots. Equivalent power output is about power output of 14,500kVA. These engines only require major overhaul after 24,000 operating hours. For high cruising speeds, GE’s popular LM 2500 gas turbine with a power output of 20MW can be activated to take the frigates F 125 up to a speed of 26 knots/ 48km per hour). MTU is the overall integrator, with Siemens handling related control systems.
Another contributor to availability is the dual redundancy/ “two island” principle, ensuring that key items are present in at least 2 different locations in case of breakdown or battle damage. The superstructure itself is split into two larger pyramidal deckhouses, as a partial reflection of this principle.
In March 2006, EADS was contracted to supply the F125 command and control and weapons deployment system, FuWES (Fuhrungs-und Waffeneinsatzsystem).
The FuWES system has an open and modular structure allowing flexibility to accommodate future additional or modified systems. In order to provide tactical data exchange and a high level of interoperability with other joint and combined military platforms, the communications systems, link 11, link 16 and link 22 are integrated into F125 command and control system. The combat management system is operated from the Atlas Elektronik OMADA consoles, designed specifically for the F125.
Guidance and surveillance will involve an active phased array radar, which will be divided between the 2 deckhouses. In addition to offering dual-island resiliency, an active array system offers all of its corollary improvements in reliability, sensitivity, and multi-targeting capabilities over passive phased array radars. Various electro-optical systems will be used for passive short range surveillance that cannot be picked up by enemy sensors.
The F125 frigates’ main armament will be a 127mm Oto Melara lightweight gun, which has the ability to fire Vulcano long-range attack rounds with a range of up to 100 km. For naval gunfire missions, the ATLAS Naval Combat System includes a very advanced onshore tactical picture and artillery weapons control system.
The gun has two automatic feeding devices (AFDs), one for the charges and one for the projectiles, the rounds being automatically assembled before entering the turret. The guns have a 35-rounds-a-minute rate of fire and a range of 23km against surface targets and 8.6km against airborne target.
GPS-capable Harpoon Block II missiles will provide the ship’s initial set of longer-range naval and land strike punch, until and unless a successor system is chosen. Two quadruple missile launchers are installed amidship on the missile deck forward of the funnel.
On the defensive front, 2 stations can mount the German-American MK44 Rolling Airframe Missile system for for short-range protection against anti-ship missiles, aircraft and helicopters, 21 cells each. For very close-in defense, each ship will mount 5 of Mauser’s 27mm MLG remote-controlled cannons, and another 5 of Oto Melara’s 12.7mm/.50 caliber Hitrole-NT RWS. These guns can counter small boats, and other asymmetric threats likely to be encountered on anti-piracy and stabilization operations. A couple of manned 12.7mm machine guns will be used as a last-ditch backup in case of power failure or other issues
The F125 is designed to support up to 50 special forces, along with space for 2 NH90 helicopters and/or 2-4 armed small boats.
Delivery of the first frigate is scheduled for 2014, and the 4th ship is slated for delivery by 2017.
Now the German Navy operates eight Bremen Class F122 frigates, which entered service between 1982 and 1990.
