japan maritime self-defense force

Hi all, I've seen a couple passing mentions of a supposed JMSDF destroyer design from the direct postwar period. This design, called "UD-2", was apparently a 3100t design with 3x2 10cm/65 and 2x5 533mm torpedo launchers. The primary documentation about this design is meant to be at the Yamato...

Currently, the Italian Carrier Strike Group "Gruppo Navale 31" after a short stop in Singapore is participating to the "Pitch Black" exercise with the Australian Navy. The CSG 31 is composed by the aircraft carirer (and flagship) ITS Count of Cavour and by the FREMM Alpino, the Cavour has a...

I've founds this interesting design on the Shipbucket forums and I've thought I share it here as well. http://www.shipbucket.com/forums/viewtopic.php?t=10014 During the Fourth Defense Force Development Plan (years 1972 – 1976), the Japan Maritime Self-Defense Force (JMSDF) planned to introduce...

https://www.nikkei.com/article/DGXZQOUA265VN0W2A820C2000000/ In the record breaking 5.6 trillion yen 2023FY budget request, the Japanese MoD has put in a request for a class of 2 new ships to utilize the SPY-7 systems originally planned to be used as AEGIS Ashore systems. The current outline...

This 2019 brainstorm from the Acquisition, Technology, & Logistics Agency seems to be still moving ahead, and is a bit odd even for that ill-starred front for the Finance Ministry (ostensible status as a MOD agency notwithstanding!). Apparently the idea was/is to enable the MSDF to be able to...

Not much in the way of details yet. Apparently in the same class as the USN's XLUUV program, though requirements haven't been nailed down yet. Presumably will be operated by the MSDF, that is, if it ever manages to emerge from the unholy mess that is the Acquisition Technology and Logistics...

Something different for today ... a collaborative project between Grumman and Shin Meiwa in Japan. Note wing engines can tilt up a few degrees (it's described on another page). Also, there is heavy reliance on active boundary layer control via twin turbines behind the rear pressure bulkhead...

Hi! Japan and the US have agreed to launch joint research on high-speed trimaran. The Japanese Ministry of Defence (MoD) announced on 4 March that it had signed a preliminary agreement on joint research into a high-speed trimaran with the Pentagon. The announcement followed the signing of a...

Hi, has anyone a more info about Mitsubishi XMH-4M helicopter project ?. http://www.geocities.co.jp/Technopolis/2415/sato.html

This was a program, possibly inspired by the B-1C and related proposals, to procure a number of P-3C based variants equipped with the AWG-9 Radar and the Phoenix missile (likely the AIM-54C ECCM/Sealed version), for the Japanese Maritime Self-Defense Force. The program began as a TRDI program in...

This is an unusual project, especially in light of known JMSDF doctrine. It was apparently conceived around the mid-'90s or there abouts by the JMSDF and the old JDA as a lower cost alternative to the procurement of futher units of the Kongō class (what would eventually become the Atago class)...

Came across this via an old article at Japan Security Watch; The JMSDF's Asuka Class ASE (Auxiliary Ship Experiment): [IMAGE CREDIT: vspg.net] The Asuka, which is the only one in her class, is an interesting testbed ship built on a Murasame class hull at a old Sumitomo Heavy Industries yard...

Dear Boys and Girls, here is an article describing the BAC X-Eleven "project" for a (then) new technology short-medium range jet airliner with CFM-56 engines. This "project" has a wider fuselage cross-section than the standard BAC 1-11. I believe this was the final attempt to make a stand-alone...

Over the years the STOVL ability of the Harrier has led to various proposals for ships for it to operate from. First was the VT Harrier Carrier concept of the mid-1970s. 8,000 tons, c. 400ft length at WL, 420 ft flight deck with ski-jump. Electric propulsion powered by 9x5000 hp gas turbine...
