   Nuclear submarine missile cruiser "Kazan" was accepted into the Navy.

   The Commander-in-Chief of the Russian Navy, Admiral Nikolai Evmenov, noted that the Yasen-M submarine is the most modern missile carrier, it embodies advanced developments.

   The nuclear submarine "Kazan" - the lead ship of the improved project 885M of the 4th generation nuclear submarines - became the 134th ship built at Sevmash for the Navy.

   The process of complete liquidation of PJSC "Black Sea Shipbuilding Plant" (ChSZ), which participated in the program for the construction of Ukrainian corvettes, has been completed. This is reported by Defense Express with reference to the report of the liquidator of the enterprise.

 

   All employees of the enterprise, built 124 years ago, were fired, all property was appraised and sold to pay off debts. 

/.../

In 2018, the economic court of the Nikolaev region decided to terminate the rehabilitation procedure for the ChSZ, declare it bankrupt and open the liquidation procedure of the enterprise.

The second Indian carrier (INS Vikrant) has started it's sea trials :

 

 

Of STOBAR configuration and design based on the experienced acquired by the Indian navy on the ex Admiral Gorchkov (Kiev class).

Displacement of about 40 000 t with a top speed of 28 knots (18 cruise) propelled by 4 General Electric LM2500+ gas turbines.

Capable of holding about 30 aircraft (among those 26 MiG-29K), it may also carry Ka-31 helicopter MH-60R.

In the future it may also carry navalized Tejas as well as either Rafale-M or F/A-18 Super Hornet (depending on how their Multi Role Carrier Borne Fighters program goes).

TIL that the Italian's Pugliese torpedo defense system was actually not that bad. The flooding issue that comes up when criticizing this system is due to it's own passive counter flooding mechanism. Pugliese incorporated several channels that ran through the triple bottom of the Littorio's that, when one side is struck and flooded, would transfer water towards the other side automatically, meaning the ship would roll less and would (hopefully) require less attention from the crew and could continue fighting. Counter flooding was normally done on all battleships after torpedo damage, to balance out the weight of the water in those compartments. Where the Pugliese (and all torpedo defense of that time) had problems is that torpedoes with magnetic fuses that ran just below the ship could do significant damage, as seen in Taranto 1940.

Edit:  I found the old paper:

 

https://catalog.hathitrust.org/Record/001622850

 

Apparently it costs around $400 million per shaft for nuc power on a surface ship.  (I've also seen 400 mil per ship).  The next gen ships need massive power for DEW, railguns, and sensors.   Their endurance on fossil fuel will be less unless innovations like electric propulsion and recuperated GT's can make up the difference.

 

Nuc ships cost more and require more personnel.  Some of the personnel are more expensive.  They can transit at top speed and do not need to slow to refuel.  Oil fired ships actually require very little time to refuel but cannot transit as fast as nucs without using lots of fuel.  Before life of ship nuc cores the nuc ships required longer refits.  The debate seems to have settled on subs needing to be nuc, aircraft carriers being better with nuc, and surface ships being oil fired.  The aircraft carrier debate was still going in the '90's and for the same $ more oil fired carriers can be had.  Maybe it was stack gas corrosion that made the decision.  One of the docs I found showed not much advantage for nuc carriers vs oil fired.

 

One intriguing idea that was not in the docs I found was making the replenishment ships nuc or even using excess power to make synfuels on the replenishment ships.

Somebody at Rubin OKB  had to much time on their hands and decided to do another take on "Strazh" proposal/concept of a submersible patrol and training vessel.  Displacement increased to 1300t  and overall length up to 72 meters.  Tops speed of 21 knots and a range of  4,000 miles at a speed of 10 knots,    Armament is a machinegun, what looks like a pair of kornet launchers and four 324mm torpedo tubes.  Additionally there are pair of hangers in the back for rotary winged UAV's and gear for boarding parties.

Without surprise the French FDI will carry less weapons than the Greek's

 

http://www.opex360.com/2022/03/23/les-fregates-belhrra-de-la-marine-nationale-seront-moins-bien-equipees-que-celles-vendues-a-la-grece/

• 76 mm
• 2x20mm RCWS
• Seafire 500 for the radar
• 8 Exocet Block 3C
• 16 Aster 30B1 (instead of 32 for the Greeks)
• 2xTwin MU90 torpedo launchers (instead of 2xtriple launchers)

No RAM or equivalent, but most importantly no jammer and reduced electronic warfare capability until at least 2026.

While the detection capability of those frigates (both in AAW and ASW) will be top of the line they'll barely have any self-protection capability (both because of the lack of jammer and possibly decoys as well as a lack of short-range missiles). They will be a nice addition to any naval task-force but will have troubles operating alone.

 

Also no increase in the number of "first line" frigates is planned. The objective remain 15 first line frigate by 2030 :

• 2 Horizon class (AAW)
• 8 FREMM (6 ASW + 2 with increased AAW capability)
• 5 FDI (ASW but with the best radar in the fleet for now)

3 FLF "second line" frigates will receive minimal upgrades while waiting for the delivery of the FDI.

Is there any future for such a concept ?

In France, there was a similar proposal : SMX-25

The question is  asked what benefit does it bring,  at what cost and worth ?  The answer i have yet to read as nobody actually has one.

Video of the first RapidFire unit (not the mock-up) at Nexter (still lacking it's sighting system which will be installed later by Thales).

Nothing new in terms of technical informations and it remain unclear whether the system can participate in terminal missile defence (and to what extent).

Another line-up of the ammunition types available with a 40mm Bofors behind them for size comparison (6:56).

 

 

First units will be installed on a ship (likely the new BRF Jacques Chevalier which was launched last month) by the end of the year or early next year. Live fire trials are expected by the end of the year.

   In Iran, the Islamic Revolutionary Guard Corps Naval Forces (IRGC Navy) officially incorporated the new Shahid Mahdavi floating base, also created by rebuilding a civilian ship, in this case the former container ship Sarvin with a deadweight of over 41,000 tons. It is named after Nader Mahdavi, a soldier of the IRGC Navy, who died in one of the clashes at sea with the Americans in 1987.
   As indicated, this is a multi-purpose ship with a length of 240 meters and a width of 32 meters on which artillery mounts and missile systems are installed, it is capable of carrying various light boats and boats, UAVs and helicopters.
   Prior to that, in 2020, the Shahid Roudaki mother ship, converted from a merchant ship, was accepted into the Iranian Navy, and the Makran mother ship, created from a tanker, was accepted into the Iranian Army in 2021.

On what kind of drones this base can possibly launch:

As a standard, they place there what can be launched from catapults / launch accelerator, such as Ababil-2 kamikaze drones, Ababil-3 reconnaissance / Ababil-4 reconnaissance-strike drones, etc. In principle, launchers of kamikaze drones like Shahed-131 \ 136 can also be placed there.

   The Shahid Mahdavi oceangoing warship is 240 meters in length and 32 meters in width and weighs 14,000 tons and has a load capacity of 41,000 tons. The warship has been equipped with a 3-dimensional phased array radar, sea-to-sea and sea-to-air missiles, advanced communication systems for electronic warfare, and cruise missiles with a range of 700 km. It is capable of carrying helicopters and drones.

   In addition, about a hundred motor boats and boats, including various missile boats, were transferred to the IRGC Navy. Among the missile boats handed over to the IRGC Navy, such one curious example - a new Iranian air defense boat. It seems that the dome is designed to protect the radar, and at the back there is a launcher for anti-aircraft missiles. It is stated that the missiles of the ship's short-range air defense system are Nawab SHORAD with a vertical launch.

Best Korea tested underwater nuclear capable drone.

Quote

   The “Nuclear Unmanned Underwater Offensive Vehicle” involved in the exercise on March 21 on the coast of Liwon County, South Hamgyong Province, during testing, cruised in an 8-shaped trajectory for 59 hours and 12 minutes at a depth of 80 to 150 meters. Then, in the second half of March 23, it reached the target in the waters of Hongwon Bay, which imitated the enemy's port, detonating a non-nuclear warhead.

   According to the statement of the North Korean side, "Haeil" can be discreetly placed on any coast, or in a port, or a surface ship.

   Pyongyang, 28 March. /CTAC/- From March 25 to March 27, the National Defense Academy of the DPRK conducted another test of the strategic underwater weapons system.
   The nuclear unmanned underwater offensive vehicle of the Hail-1 type, involved in the test on the afternoon of March 25 in Wonsan Bay, swam under water in 41 hours and 27 minutes along a sawtooth and oval trajectory defined on the East Korea Sea with a length of 600 kilometers. And in the morning of March 27, it reached the intended target area - the sea in front of Hwade County, North Hamgyong Province, where its test warhead wad detonated under water.
   As a result of the test, all the tactical and technical characteristics and underwater movement technical indicators of this system were accurately assessed, and its reliability and safety were confirmed.

   Pyongyang, 8 April. /CTAC/-- A competent defense research institution conducted a test of a strategic underwater weapon system from April 4 to 7.
   The Haeil-2 type nuclear radio-controlled submarine attack vehicle involved in the test on the afternoon of April 4 in the Kajin port of Geum county, South Hamgyong province, swam under water for 71 hours and 6 minutes along the oval and 8-figurative trajectory with a length of 1000 kilometers. And on the afternoon of April 7, the device arrived at a given sea area, the sea in front of the Ryongdae port of the city of Tancheon, South Hamgyong Province, where its test warhead exploded under water.

 

   As a result of the test, the reliability of the system of underwater strategic weapons and its ability to deliver a fatal blow were verified in full.

   This system, which is necessary for deterring the enemy's growing military actions, eliminating the threat and protecting the DPRK, will become an excellent military potential of our promising armed forces.

Let me remind you that the name Haeil in translation means "Tsunami" and if in previous cases the underwater unmanned apparatus "Haeil-1" was tested at a distance of up to 600 km, then the second version of the apparatus - "Haeil-2" was already tested at a distance up to 1000 km.
