Early Cold War Destroyer challenge

[odysseus1980]

Yes, last one is very nice. Well done Rodondo!

Superboy has also a very good design, conserning the limited funding of his AU.

As stated previously, I'm willing to extend our deadline to Sept 15th if people need more time. There have been some really awesome entries in here and I want to make sure everyone has a chance to post/be included if they want.

[odysseus1980]

This would be useful, I have in my shipyard something.

[Muscatatuck]

An extension would be very much appreciated.

IJN Asashio DDE refit in early 50s


With the start of the cold war in late 1940s the IJN naturally felt it needed new ships to deal with the emerging threat of fast Soviet submarines developed from the captured KM Uboats gained at the end of WWII just prior to the armies meeting on the Oder.
The diet was naturally somewhat dismissive of so much spending just after the war and therefore the IJN had to look to its relatively new and numerous but now obsolescent DD classes to fill its fast escort needs.

The 10 Asashio class only completed in 37-39 so had hulls and engines only 10 years old but the old 5" guns through officially designed as DP now where obviously too slow and infective against new fast aircraft threats emerging so offered ideal hulls for conversions. With the cooperation continuing from the war of the other big three treaty navel powers they started work on proposal's for frigate conversions. Twin 10cm mounts where reused from spares freed up from modifications to compensate for increased ASW and Radars top weight to later DD classes.

The result the Asashio DDEs completed conversion between 52-55 and served mostly into the early 70s

Asashio DDE specifications as converted:
Displacement: 2,700t
Propulsion: 2-shaft geared turbine, 3 boilers, 50,000 shp (37,285 kW)
Speed: 32 knots (40 mph; 65 km/h)
Range: 6,400 nmi (10,600 km) at 15 kn (28 km/h)
Complement: 192
Armament:
2 × 10 cm/65 (3.9") Type 98 (1 x 2)
6 x 40mm Type 1 AA gun (3x2)
5 × Type 96 AA guns (5 x 1)
4 × 21 in fixed torpedo tubes (2 × 2) with 12 × Type 12 torpedoes
2 x ASM Mortar Type 15 (limbo MK10) (some early ships revived Type 4 mortars as standbys until mid/late 50s)
Towed decoy system fitted in stern
Radar, Electrical and ASDIC systems where a mixture of home grown and mostly RN due to the cost of US systems being to expensive for the IJN budget for secondary craft and the availability of outstanding semi blocked sterling balances from the war.


Thanks to BB1987 for the hull and Rainmaker for inspiration.

Not worry gents - I'm happy to extend the contest to September 14th Updated the OP too. Same rules apply.

[BB1987]

Thanks, my entry was so far from being finished that it wouldn't be ready in time in any way. Now there is some chance

[Yasutomi]

Although my design has its own thread, I would still like to include it in the challenge that inspired it...not that it's in the same league as the other entries!



2x 5"/54 Mark 39 single mounts
4x 3"/50 Mark 27 twin mounts
1x 21" Mark 15 quintuple torpedo tubes
1x Mark 11 Hedgehog ASW mortar
4x K-gun
2x depth charge racks

If the contest is extended and I have some time next week, I will try to work up a little background material and edit it into this post.

The Vrijstaat navy always showed a great interest in aviation capable warships, owing much of the interest was the large expanse of ocean separating the various islands of the Vrijstaat Archipelago.
The various float planes previously used gave way to helicopters of varying sizes, all geared to hunting submarines as well as search and rescue.
The Type 84 destroyers were large destroyers which had an almost uninterrupted flight deck, albeit too small to operate fixed wing aircraft.
To complement the embarked helicopters, the ship was armed wit 3X1 100mm guns in bug gun-houses, two Sea-Cat missile systems and 'Bidder' Anti-Submarine torpedoes. 4 20mm Oerlikon guns were also carried.

Interesting design does the type 84 have a hangar (and what hight is it?) or just a deck park?

Also what date is it I'm guessing very late 50s?
