Littoral Operations

I Corps's 25th Infantry Division, out of Hawaii, is currently one of the US Army's lead experimental forces. I lost its Strykers and it is down to two brigades mounted on ISVs. It has lost its Cavalry and each MBCT consists of three infantry battalions and a Multi-Function Reconnaissance Company.

The Brigades have lost their integral artillery battalions but those battalions have been pulled back into the DivArty and reconfigured. Before they were two equal battalions with two M119 batteries of 6 and an M777 battery of 6. Now one battalion has two M119 batteries of 8 and its 6 gun battery of M777s while the other battalion, which also retains its 6 gun battery of M777s has swapped its M119 batteries for 2 batteries of HIMARS with 8 launchers to the battery.

The DivArty also has another couple of battalions under command. A signals battalion and the 125th Intelligence and Electronic Warfare Battalion.

That battalion got a work out in the recent exercises in the Phillipines.

One of its responsibilities was deploying and supervising a swarm of boat sized USVs to cover the movement of Army LSVs in the operational area.


"The strategic geography of the Philippines makes this capability development particularly relevant to regional security planning. The country consists of more than 7,600 islands spread across a maritime area larger than the Mediterranean Sea, and any military force trying to move equipment, supplies, or personnel between those islands must accept significant exposure to maritime observation. Autonomous vessels that can extend surveillance coverage across those waters without requiring a corresponding number of manned ships or aircraft represent a direct answer to the problem of managing a vast maritime geography with limited resources."
 
“The world needs tens of thousands of these (USVs),” he said. “There are only hundreds floating around today.”



While aerial drone markets are becoming increasingly crowded, Red Cat sees maritime autonomy as a sector still in its infancy. That opportunity is being pursued through BlueOps, the company’s maritime subsidiary led by president Barry Hinckley.

“The world is three-quarters ocean,” Hinckley told Shephard. “Many of the areas that the US and its allies are interested in are surrounded by water, and you cannot get there with a road.”

BlueOps is developing a family of USVs that it believes could offer a lower-cost alternative to traditional naval platforms for surveillance and maritime security. According to Hinckley, the market remains significantly underdeveloped.

“The world needs tens of thousands of these,” he said. “There are only hundreds floating around today.”

....

One of the more notable areas of focus identified by BlueOps is South America.

Rather than concentrating solely on large Western naval powers, executives pointed towards countries with extensive coastlines but limited budgets for major surface combatants. Argentina, Brazil, Chile and Mexico were all highlighted as potential future operators.

“Large countries that are allies with small budgets can now get legitimately in the game of coastal protection,” Hinckley said.

I'll stick this here but it applies to all UxS systems. Navigating without GPS.


And I know it is an ad.

Further to....


"Honeywell Alternative Navigation Architecture (HANA) — a software-based solution designed to ensure resilient navigation for crewed and uncrewed aircraft, as well as military surface vehicles, in environments where Global Navigation Satellite System (GNSS) signals are degraded, jammed or spoofed."

"HANA is a multi-system navigation platform that includes:

"Vision-aided navigation: Using live camera feeds to match ground imagery with map databases.
"Magnetic anomaly-aided navigation: Detecting known variations in Earth’s magnetic field.
"Low Earth Orbit (LEO) satellite navigation: Offering stronger, lower-altitude signals more resistant to jamming.
"Other modalities: Including light detection and ranging (LiDAR), radar, radios and star trackers.

"With this layered architecture, operators can mix and match modalities to meet mission-specific requirements, ensuring maximum resilience, system integrity and consistent availability even in GPS-denied environments. To ensure efficiency and ease of use, HANA can run on the operator’s current computing platform, or one that Honeywell provides.

"The initial release of HANA includes vision-aided navigation, but Honeywell also plans to integrate magnetic anomaly and LEO satellite solutions into the platform in 2026."
 
So back to Littoral Operations based on the latest input from the UK's Defence Investment Plan

The RN is revisiting its amphibious transport situation.

Currently the RN operates

2 CVs capable of lifting 250 to 900 troops
3 LSD(A)s capable of lifting 350 to 700 troops
8 OPVs capable of lifting 18 to 50 troops

The Type 45s, 26s and 31s have the ability to lift about as many troops as the OPVs.

There was an intention to build something in the 25 to 40,000 tonne range to support 3 Commando Brigade but that brigade has been refashioned into the UK Commando Force of two Littoral Response Groups and reroled for dispersed long range raids rather than concentrating for a shock landing. Its new connectors, the Commando Insertion Craft - is a totally enclosed 60 tonne vessel of 24 m capable of landing troops and small vehicles over high seas at 40 to 50 knots. A lot of emphasis on UxV support.


This has resulted in the RN downsizing its requirements and putting it back in line with the Dutch Navy's Amphibious Transport programme.


Instead of the 25 to 40,000 tonne LPDs sought by the RM/RN the Dutch were seeking something smaller. They were seeking to replace their LPDs (12-16,000 tonnes) and their OPVs (3700 tonnes) with something estimated to be in the 7-10,000 tonne range with a length of 150 meters. They are expected to have flooding deck wells and large flight decks and crews of 60 to 70. Damen has received the contract to build something based on their Enforcer series with is related to both the Dutch LPDs and the British LSD(A)s.


Interestingly Damen has just completed a 107 m, 7000 tonne Multi-Role flat top for the Portuguese navy designed to support UxV operations.
That vessel has a crew of 48 and was built at a cost of 132 MEuro. It has a carrying capacity of 300 troops,


Ships being replaced

Johan de Witt (176 m, 15500 tonnes, 146 crew, 555 troops)
Rotterdam (166 m, 12750 tonnes, 139 crew, 595 troops)
Bay (176 m, 16,200 tonnes, 70 crew, 350 to 700 troops)


Holland (108 m, 3750 tonnes, 54 crew, 40 pax)


....

This bit falls into pure speculation - if the Dutch are looking to a vessel to support distributed operations, including replacing their OPVs, and if the Brits and the Dutch have been using their OPVs and LPD/LSDs to support hybrid operations then is it possible that the Brits, who are looking at what they do with their own OPVs might consider covering off some of their OPV duties with this same vessel?

River (90 m, 2000 tonne, 34-50 crew, 50 troops)


Options under consideration include replacing the Batch 1s with a new Batch, buying more, building more Type 31s in simpler configurations or doing something else.

...

The Dutch spec calls for a crew of 60 to 70, similar to their Hollands, not much more than the Brit Rivers and about the same as the Portuguese Multi Purpose.

And the Portuguese ship was built for 132 MEuro, the Hollands were built for 117 MEuro in 2012, the Rivers Batch 2 for 116 MUKP in 2014.

The Dutch LPDs were built for 260 Mio Guilders in 1996-2007 and the Bays were built for 149 MUKP from 2002-2007.
