The first PLAN Type 039 submarine was recently observed with some curious cradle mounts on its stern hull.

Analysis of the waterline mark and measurements confirms that the new-construction submarine Khabarovsk is closely related to the Borei-A (as expected), but also that it sits much lower in the water. This likely means that it has much less reserve bouyancy.

This photos, showing a torpedo launched from an XLUUV (it’s not fully submerged, that’s normal for this stage of trials), puts the Indonesians ahead of all Western countries in this regard! Why are European navies sleeping?!?!

Access and filming aboard submarines is usually very rare and restricted. Many thanks to the Italian Navy for giving @navalnews.com this exclusive and detailed tour during Sea Future 2025.

People think that the propeller (aka screw, propulsor, pumpjet) is the most sensitive part of the submarine, and is always hidden at launch. No more. Now it’s all Russia wants to show because the weapon system is way more sent sensitive

With all this talk about nuclear tests, Poseidon, Burevestnik, etc. lately, it’s time for a British classic to remind everyone that the more things change, the more they stay the same…

1/ In September 2025, the inaugural Drone Crucible organized by the US National Drone Association brought together teams from Army Rangers and Aviation Center of Excellence, Navy SEALs, Air Force and the Marines. Thanks to @dflawrence.bsky.social for the summary: taskandpurpose.com/tech-tactics...
No clear winner in military's first ‘drone crucible’
Teams from each service went head-to-head in training events for unmanned systems, including convoy ambushes and reconnaissance.
