1000 Ton Korvette



The 1,000 ton corvette was an early 1970s project to provide a control ship for a mixed force of FACs and helicopters. This design was by Entwicklungsburo Poseidon Kiel GmbH and construction would have been by Howaldstwerke.
The Bundesmarine changed its mind about the operating mixed force concept and so the design was offered for export, Greece being one proposed customer, but no sales materialised.

Displacement: 1,075 tons
Length: 79.5m
Armament: 8x Exocet SSMs, 2x 76mm OTO, 2x 20mm Rhienmetall
Electronics: Vega fire-control with Triton search radar and 2x Pollux trackers, Ferranti CAAIS with a Collins datalink
Propulsion: CODELEG - 2x 22,000hp RR or GE gas turbines, 2x 19,250kW turbo-generators supplying 2x 1,350kW 2-3 phase Siemens electric motors (used for cruising only)
Speed: 40kt
Range: 2,500nm at 18kt (ship designed to stay at sea for 5 days)
Crew: 8 officers, 34 petty officers, 20 ratings

Klasse 121 Fregatte 70



Originally ten Tartar-armed corvettes were desired but this proved both unaffordable and unfeasible given the size of ship required. In 1968 work shifted to four air defence frigates to replace the ex-USN Fletcher-class destroyers and approved in January 1969 by the German parliament. The larger ships proved equally expensive and were cancelled in early 1971 in favour of the Type 143 Albatross FACs. The design ended up very similar in several respects to the Dutch Tromp of the same period. Another factor may well have been that the three Lutjens-class (Charles F. Adams) destroyers entered service in 1969-70 which provided the air defence the Bundesmarine was seeking.

Displacement: 3,200 tons (standard), 3,600 tons (full load)
Dimensions: 134 x 13.7 x 4m
Armament: 1x Mk 13 launcher for 40x RIM-24 Tatar, 4x 76mm OTO, 4x torpedo tubes (these seem to be fixed fantail tubes)
Electronics: includes AN/SPS-01 3-D air search radar, 2x WM-25 fire control radars and 2x AN/SPG-51C illuminators
Propulsion: CODOG
Speed: 30kt
Crew: 250

Excellent entries. I hope to see many more in this thread!
Btw. the location of forward Exocet launchers on the 1000t Korvette is pretty original to say the least.

Great work Hood - I have to echo Eswube's comments, that missile corvette is interesting to say the least! It's also great to see the Type 121 getting a much-needed re-draw.

I find it interesting to see how different design choices can produce a radically more capable design. The Dutch managed to fit both Sea Sparrow for close-in air defence and a small helicopter hangar on their Tromp - class, while producing a warship that was only ~450 tons heavier based on standard weight. A Type 121 with a Tromp-style flush deck and combined helicopter hangar/Mk 13 launcher would make for an interesting Alternate Universe design.

The Klasse 121 Fregatte 70 has been redrawn has it was 4m too short before!

Cool. Now this is good show of work etique, we all should aspire to achive.
