When did that happen, i haven't heard such information. Very unlikely considering the Japanese constitution.

Do you have any details? As far as I know Japan is prohibited from selling or transferring any major defense equipment.

Japan changed constitution, forgot that ? Japan also selling aircraft to Indian Navy.
and no, i don't have details

That's true, they did change their constitution recently. Not sure if we need destroyers right now (most of their early destroyers are actually the size of frigates), the only ones I can think of are either the Hatsuyuki class or the Asagiri class.

most possibly that's a bluff. And we have no appetite to accept a ship that is run by COGOG propulsion. It will be disasterous for us. We always use CODAD propulsion on our vessels.

I highly doubt the authenticity of this news. If japan sells any military equipment, it would be all over the international media. Plus i dont see them arming us any time soon, especially since they have spent a lot of money to provide aid to us.

jmsdf first used WW2 era US Gleaves and Fletcher class destroyers, then build similar ships at home starting around mid-1950 (Harukaze, Akizuki). Japanese destroyers built since 1980 start at over 4000 tons (Takezuki/Hatsuyuki/Amatsukaze/Tachikaze) and quickly move to 5000 tons (Hatakaze/Asagiri) and then 6000 tons full load (Murasame, Takezuki) to 7000 tons (Akizuki) today

Mid 1970s you also had the DDHs of the Haruna and Shirane classes, at 7000 tons.

And then there are the Arleigh Burke like Kongo and Atago classes, of arounod 10k tons.

Destroyer Escort / Anti Submarine Destroyer: mostly frigates actually

I have a feeling this will be a smaller 4000 ton Destroyer (maybe Hatsuyuki class) that is going to be refurbished and transferred to BN a la Minerva class instead of being de-commissioned. Although the refurbishment may happen locally in Bangladesh instead of in Japan, considering the high labor cost in Japan.

BS.Even after Japanese constitution amendment Japan can only sell non lethal equipment.So it is never going to be a destroyer.Patrol ships are a possibility.

Since 2010, 6 of this class of 12 ships has been decommissioned, with 6 remaining in service, of which 3 as training vessels. One ship was decommissioned in 2010, one in 2012, two in 2013 and two more in 2014.

As of March 5th 2013, it was being reported that the Japanese government were considering the transfer of four small destroyers [frigates] (later confirmed to be of the Hatsuyuki class) from the MSDF to the Japan Coast Guard, in light of the extreme strains on the latter's resources due to current events. Of the four, one has already been decommissioned (in March 2013), with the other three to decommission over the course of FY2013. If the transfer goes ahead, the four vessels will likely be modified to JCG requirements (e.g. removal of the Harpoon launchers) and redesignated as PLHs.

See also e.g. Coast Guard to pick up retiring Hatsuyuki-class destroyers? | Japan Security Watch
Given decommission dates, these four are DD-124 Mineyuki, DD-125 Sawayuki, DD-127 Isoyuki and DD-128 Haruyuki

This leaves DD-122 Hatsuyuki (decommed 2010) and DD-126 Hamayuki (decommed 2012)
Apparently, these probably were not up for transfer from JMSDF to Japan Coast Guard.
One can speculate why (e.g. ship age, degree of usage, ship condition etc)

What with the third Hamilton class cutter on the way and the Hatsuyuki class boat(s), Bangladesh Navy will be awash with old boats like the OHP class. These have to be interim force additions because the max life of these vessels will be maybe another decade at most.

Sizewise like @Penguin bhai said these are more like large frigates - however they are armed to the teeth like destroyers. I don't discount Japanese shipbuilding expertise. As of 1940's they claimed the world's largest battleship (Yamato) and the world's fastest battle cruiser, way faster than anything the US had in its fleet (name escapes me at the moment).

Was it Shimakaze? Wiki link.

[Shimakaze (島風?) (Island Wind) was a one-off super-destroyer built for the Imperial Japanese Navy during World War II. She was armed with six 127 mm (5.0 in) dual purpose guns and conventional anti-aircraft and anti-submarine weaponry. More importantly, she was the only Japanese destroyer to be armed with 15 torpedo tubes each capable of firing the deadly 610 mm (24 in) Type 93 "Long Lance" torpedo. The ship was a testbed for an enormously-powerful, high-temperature, high-pressure steam engine that was able to develop 79,240 shp (59,090 kW). This made her one of the fastest destroyers in the world: her designed speed was 39 kn (72 km/h; 45 mph), but on trials she made 40.9 kn (75.7 km/h; 47.1 mph).]

COGOG (Hatsuyuki) is more expensive to operate than CODOG (Hamilton) - no ? But why?

@Penguin Bhai Thanks for the BDMilitary link. The image is definitely that of a Hatsuyuki class (like I've mentioned before) but what is the assurance that it will be that specific vessel class? BD Military has been known to slap on any oddball image at its convenience....

Without confirmation on this from an official japanese source, I am not yet willing to accept there will be an actual transfer of a Hatsuyuki class SHIP (a boat is either small or a submarine ;-) and even if there is a transfer, it would remain to be seen what it would come with in terms of weapon and sensor systems.

Sizewise like @Penguin bhai said these are more like large frigates - however they are armed to the teeth like destroyers. .

They are referred to a 'small destroyers'. Their armament and sensor fit is quite comparable to contemporary frigates e.g. the Dutch Kortenaer class, German Bremen class, British Type 22, Italian Maestrale class, Meko 200, US Perry class frigates. And French Cassard class destroyer. Destroyer or frigate is predominantly a function of intended role ( > necessary capabilities > systems > size).

Sizewise like COGOG (Hatsuyuki) is more expensive to operate than CODOG (Hamilton) - no ? But why?[/USER]

Is that so? While COGAG as on e.g. Ticonderoga class (4 LM2500) is definitely less fuel efficient than a combination of high speed GTus in combination with cruise GTus or diesels. See e.g. Ship Hull and Machinery Optimization Using Physics-Based Design Software, JIANG, 2002 - StevensInstituteStudentSection

I doubt though that the difference between COGOG on Hatsuyuki and CODOG on Hamilton is of the same order of magnitude. For one, the GTus and diesels on Hamilton are of a previous generation.

No assurance what soever. Hence my first statement: needs confirmation on this from an official japanese source[/USER]
