It will be interesting to see what the result of the investigation will be. This accident reminds of the time that Astute-class boat had a bump with a commercial ship, although the damage was much less for the A-boat. I expect it can only be human error and/or an unfortunate combination of events where the sonar/periscope couldn't detect the ship.

Regardless, probably a big strike against the commanding officer’s career future.

I love the comment .... only minor damage .... the very bent forward hydroplane suggests minor may be an understatement as the damage is sufficient for a RTB and quite a bit of work even if there was no pressure hull damage.

The Oberon's used to practice underwater looks on ships. This is just what is sounds like .... go a bit deeper ... let the ship go over you .... and have a look through the periscope to capture information on hull fittings etc. It was practiced .... normally with friendly warships.

A Bulk Carrier underway (even at anchor) would generate a LOT of noise. I cannot believe for one second they did not hear it and track it. It will be interesting to see what the investigation turns up (if it is reported).

Yeah, I've now looked at the map where it happened more closely, and it looks far enough off shore they can't complain about the water being shallow, etc., so it will be difficult to defend as a no-fault collision. What you say about an attempt to go under the ship makes more sense.

Certainly the officer in charge will find it difficult to get a good posting after this.

JMSDF commissions new Hibiki-Class SURTASS / Ocean Surveillance Ship JS Aki - Naval News

A new ocean surveillance ship, JS Aki (AOS-5203), was commissioned by the Japan Maritime Self Defense Force (JMSDF) on March 4, 2020.
www.navalnews.com www.navalnews.com

Quite a unique class of ships, but they are actually some kind of ASW-data gathering ships. Also unique is the fact that between the commissioning of the second and third ship, there are more than 28 years.

It has a helipad but no weaponsystems.

The Maya-class will be limited to just two ships. The next Japanese vessels to feature Aegis are the still unspecified “Aegis equipped ships” that will likely be ordered as a consequence to the cancelation of Aegis Ashore.
Big chance that the new class will become even larger and heavier with also more VLS-cells.

The final Soryu class SSK has been launched. Like boat number 11, boat 12 has Li-ion batteries. It will be interesting to see the next evolution of the Japanese SSK. In the unlikely event Canada renews its submarine fleet, the future Australia/France design or a future Japanese sub with increased range would be the most suitable for the RCN.

I think the Japanese subs may be a good fit for Canada and its CONOPs. If you want a conventional sub with exceptional submerged endurance, an extremely strong hull, to operate around Canadian EEZ. That would be a reasonable fit. However, Canada would still most likely have to produce locally. Japanese sub production is pretty much maxed out for local consumption with their two current lines. I would also hazard the Japanese are perhaps a bit shy about offering subs.

Yes, availability from Japan likely would be problematical and from Australia too. Local build, not practical unless we plan a 2-3x fleet expansion. If the fleet is renewed it will be 4 German subs with inferior capability to the alternatives above.

JCG will proceed with specific studies to introduce unmanned aerial vehicles (UAVs) to conduct maritime surveillance and other operations.


This is a logic move of the Japanese Coast Guard, improving its capabilities in an cost effectice way. The General Atomics SeaGuardian will be the strongest candidate.

Big chance the navy (JMSDF) will follow soon.

Japan has three in the water now.

13 months, 16 months (after an accident while building) & 11 months from laying down to launch for the first three. They work fast. The fourth is due to be launched any day now, & there were four more under contract the last I heard. Building at two per year.

Two days ago there was an Indonesian newsreport about this rescue operation, but it was a confusing article. Now the JMSDF has posted a Tweet about it in understandable English.

Japan has started Pacific Vanguard 2021, together with the navies of Australia, South-Korea and the US. It is a quite large exercise with a lot of different maritime activities including anti-submarine warfare, air warfare, live-fire missile events, and advanced maneuvering scenarios.

I was assuming they are cake. /s/
Though, that was last year's craze, so maybe not.

Got this video from the link on Naval News (Xavier) site. However the video coming frm official Japanese ATLA sites. Eventough it talk of Japanese near future defense capabilities, but it cover more on maritime defense. Thus I put it here.


Quite interesting on their new OPV design. Seems asside from enlarging their Frigate forces, from traditional heavy development on Destroyers, they also enlarging patrol force with OPV. Seems this is their (JMSDF) answered for more policing work.

The first phase of the modification program to make the ship capable to operate the F-35B is finished.

The second phase of modification is scheduled for the end of FY2024. In this second modification, the bow shape of the Izumo will be changed from the current trapezoidal shape to a rectangular shape to make it easier to operate the F-35B, and other changes to the ship’s interior compartments are also planned.
