Maritime Coastal Defence Vessels (MCDVs)

What is the thinking behind this bow design?
New Italian Patrol Bessel P430.


A 'wave piercing bow' apparently:

"The new units reach a maximum speed of over 32 knots also thanks to the particular shape of the bow, designed to maintain high speeds even in rough seas. The range is 5000 nautical miles at 15 knots of speed…"

What is old is new. Been used on certain kayaks for a thousand years

It should be noted that there is no MCDV or submarine replacement project or funding on the DND investment plan (may have the name wrong) or in the white paper so on the big picture level there is nothing on the books outside of what is already in NSS for the RCN.

Know CRCN is really gung ho about both, but think he's massively overconfident on both of these, especially as we don't have sailors for our current fleet of subs, and continue to shrink. I think the big cuts for next year will be a shocking dose of reality.

The fact we only have one sub that is actually capable of going to sea might have something to do with that.

Technically incorrect....we have 4 subs....and we could probably put 3 of them to sea (depending on current maintenance status) but would probably only get one of them back (again, depending on current maintenance status.)

Really more lack of qualified crews, regardless of the maintenance status, but the cuts will impact the sub budget as well so expect some announcements there as well.
 
A new Portuguese entry into the field?


Coastal Patrol trimaran optimized for uncrewed systems - small hangar, large deck and large mission bay accessible from port, starboard and stern. 500 to 1000 tons.


The new navy will be built around these patrol vessels, submarines and 7000 tonne Multi Purpose Support Ships

NRP D. João II, also known as the Multifunctional Naval Platform, will be a multipurpose ship for the Portuguese Navy, capable of carrying out surveillance operations, oceanographic research, environmental and meteorological monitoring, as well as emergency evacuation missions.[1]

 
I debated putting this in one of the "Drone" threads but every thread seems to becoming a "Drone" thread.


The US Navy announced that four industry teams have completed an engine reliability test as part of the Large Unmanned Surface Vessel program, a wonky-but-crucial mile marker that has had lawmakers’ attention since the program’s inception in 2020.

The four shipbuilders, each of which worked with different facilities to accomplish their respective tests, were Bollinger, Fincantieri Marinette Marine, Gibbs & Cox, and HII.

“Demonstrations of each engine configuration took place over 720 continuous hours,” according to a March 22 Navy statement. “No human intervention or preventative/corrective maintenance on the equipment was permitted during this time. Successfully completing the demonstration meant that an engine system could not exhibit any failures or issues that would require maintenance of any kind during operations on an unmanned ship for 30 days.”

Successfully passing the reliability testing is a requirement for an engine to qualify for use in the final LUSV program, the statement added.

LUSV is envisioned to be longer than 200 feet in length with a full load displacement of approximately 1,500 tons. The program of record was formally introduced in the 2020 budget request with ambitious timelines for fielding a fully-fledged unmanned ship capable of adding to the fleet’s magazine capacity as well as wielding a variety of payloads.

So a 1500 tonne ship that doesn't require intervention in the engine room for 30 days. One way to use that is have an uncrewed vessel. Another way to use that is to have a lightly crewed vessel with a crew with reduced training requirements.

A crew more like an Orca crew than an MCDV crew.
 
. . . a ship that doesn't require intervention in the engine room for 30 days. . . .

MV Dali enters the chat?

Though vessel finder is a little slow to update its description of the location.
The current position of DALI is at US East Coast reported 1 min ago by AIS. The vessel is en route to BALTIMORE-COLOMBO, and expected to arrive there on Apr 22, 11:30. The vessel DALI (IMO 9697428, MMSI 563004200) is a Container Ship built in 2015 (9 years old) and currently sailing under the flag of Singapore.
