Royal Australian Navy Discussions and Updates 2.0

Has an announcement been given by the RAN on what happens with Harpoon missiles replaced by the N.S.M either kept as war stock or given to some country that might find a use for them

I believe that a decision has been made to NOT equip the Collins class with Tomahawks as part of the planned LOTE and the NSM currently does not have an underwater launch capability so, the Harpoon looks like remaining in service with the RAN for the foreseeable future (with a good number available).

Also, the P-8 is still using them but JASSM-ER & JSM are currently being trialed for release from the P-8 so, it’s just a matter of time before they are retired from RAAF service.

I think it's a valid concern. To your point, killing a submersible drone with a MK48 torpedo is akin to shooting down a Shahed aerial drone with a PAC3 MSE.

A Collins holds I think 20 torpedos as a full load. A Virginia does not hold a lot more. So what does it do if there is more than 20 drones.

Traditional anti submarine warfare is aligned with hunting a lone tiger. The game changes if it's a pack of hyenas.

The answer is already in development, Compact Rapid Attack Weapon (CRAW).

Northrop Grumman Reveals New Mini Torpedo That Could Arm Navy Submarines In A Few Years

The mini-torpedoes could be a game-changer and are set to be fielded on Virginia class submarines in the next few years.

Also manned submarines have been seen as future UUV, even UAV, motherships.

I can't help but think we are on the cusp of a change in undersea warfare. These drone subs are equal or better to dipping sonar and sonobuoys. They can be fitted with towed arrays and coordinate with each other.

Unlike other procurement activities, we will have a capable force of ghost sharks within a year, and an armada within 3-4 years.

How does a crewed submarine deal with a large pack of these. It would not be hard to saturate an area of ocean with them.

Crewed subs work on the ability to stay hidden because they can't outrun threats. I think a large pack of ghost sharks could make it hard to hide, and turn the ocean into a giant spotlight.

No ability to hide under thermoclines. No ability to avoid active sonar. Too many to fend off. Too persistent to outrun.

In addition to that, don’t forget that Anduril has designed the Ghost Shark to deploy and retrieve their Seabed Sentry sonar system. The Ghost Shark is modular allowing extension sections to be added thus increasing the number of these systems that can be deployed during a single deployment. This is looking like a very capable system and I can see the RAN purchasing more Anduril products as they deliver bang for buck.

I understood the Anzac class frigates and Hobart class destroyers are equipped with Harpoon missiles

What would be involved with using the Harpoons on other platforms? The CMS has to be up to par.
