Below is a news release from Northrop Gruman. The gun has been around since 1973 when developed for the AH-64 Apache attack helicopter, but the dual feed is new. While they say the single feed and dual feed share 60%-part commonality, that means they are 40% different so there are significant changes.

Dual feed is a big deal because it means a gun in a remote weapon station can now be ready to deal with both surface and air threats.

I’m pretty sure, the Coast Guard wants to be able to counter drone attacks–both air and surface. This weapon, used in a remote weapons system, is small enough to be considered a .50 caliber replacement, and it would be much more effective against both air and surface threats.

Naval News has an excellent interview with Vice Admiral Juan Ricardo Rozo Obregon, Chief of the Colombian Navy. It covers many topics of common interest with the US Coast Guard.

He mentions an intelligence sharing system I was not aware of.

Currently, we have developed capabilities in information systems and software development, reaching a high degree of technological independence. This autonomy has allowed the creation of advanced technological solutions with our own resources, reflected in the digitalization and automation of processes. An important example of these advances is the development of the Orion Platform, which integrates drug trafficking information from more than 62 countries worldwide, registering alerts and operational results with real-time visualization and monitoring.

Also discussed is Colombian Navy support of Antarctic research.

An accompanying illustration of one of the five Damen designed light frigates Colombia is building gives us a bit more indication of how they will be armed. There is a 76mm on the bow, a 16 cell vertical launch system, quad cruise missile launch tubes between the bridge and the stacks, and a BAE 40m Mk4 well aft on top of the hangar. They will probably have ASW torpedo tubes as well.

The Congressional Research Service has once again updated their look at the Polar Security Cutter (heavy icebreaker) program. Also included are looks at the Great Lakes and Commercial Icebreaker procurement efforts. (See the latest version here.)

I have reproduced the summary below.

The news here is that there is so little news.

• Polar Security Cutter, “The Coast Guard’s proposed FY2025 budget requests no procurement funding for the PSC program.”
• Commercially available Polar Icebreaker, “The Coast Guard’s proposed FY2025 budget requests no procurement funding for the CAPI program.”
• Great Lakes Icebreaker, “The Coast Guard’s proposed FY2025 budget requests no procurement funding for the program.”
• Arctic Security Cutter (the Medium Icebreaker), the PSC is “to be followed at some later point (emphasis applied–Chuck) by the acquisition of new Arctic Security Cutters (ASCs)…“

GAO has been saying the Coast Guard cannot possibly build the Polar Security Cutters for the price currently contracted. The shipyard has been building some sample sections. I suspect that part of the reason is to find a more realistic estimate of how much they will cost. “If substantial cost growth occurs in the PSC program, it could raise a question regarding whether to grant some form of contract relief to the PSC shipbuilder.”

Note, there is still no publicly available information from the 2023 Fleet Mix study, other than the required number of icebreakers. Why not?

SUMMARY

Required number of polar icebreakers. A 2023 Coast Guard fleet mix analysis concluded that the service will require a total of eight to nine polar icebreakers, including four to five heavy polar icebreakers and four to five medium polar icebreakers, to perform its polar (i.e., Arctic and Antarctic) missions in coming years.

Current operational polar icebreaker fleet. The operational U.S. polar icebreaking fleet currently consists of one heavy polar icebreaker, Polar Star, and one medium polar icebreaker, Healy. A second Coast Guard heavy polar icebreaker, Polar Sea, suffered an engine casualty in June 2010 and has been nonoperational since then. Polar Star and Polar Sea entered service in 1976 and 1977, respectively, and are now well beyond their originally intended 30-year service lives. The Coast Guard plans to extend Polar Star’s service life until the delivery of at least the second Polar Security Cutter (PSC; see next paragraph).

Polar Security Cutter (PSC). The Coast Guard Polar Security Cutter (PSC) program aims to acquire four or five new PSCs (i.e., heavy polar icebreakers), to be followed at some later point by the acquisition of new Arctic Security Cutters (ASCs) (i.e., medium polar icebreakers). The Coast Guard in 2021 estimated PSC procurement costs in then-year dollars as $1,297 million (i.e., about $1.3 billion) for the first ship, $921 million for the second ship, and $1,017 million (i.e., about $1.0 billion) for the third ship, for a combined estimated cost of $3,235 million (i.e., about $3.2 billion). The PSC program has received a total of about $1,731.8 million in procurement funding through FY2024. The Coast Guard’s proposed FY2025 budget requests no procurement funding for the PSC program. One oversight issue concerns the accuracy of the PSC’s estimated procurement cost, given the PSC’s size and internal complexity as well as cost growth in other Navy and Coast Guard shipbuilding programs. If substantial cost growth occurs in the PSC program, it could raise a question regarding whether to grant some form of contract relief to the PSC shipbuilder. Another oversight issue concerns the delivery date for the first PSC: the Coast Guard originally aimed to have the first PSC delivered in 2024, but the ship’s estimated delivery date has been delayed repeatedly and may now occur no earlier than 2029.

Commercially available polar icebreaker (CAPI). The Coast Guard’s proposed FY2024 budget requested, and the FY2024 Department of Homeland Security (DHS) Appropriations Act (Division C of H.R. 2882/P.L. 118-47 of March 23, 2024) provided, $125.0 million in procurement funding for the purchase of an existing commercially available polar icebreaker (CAPI) that would be modified to become a Coast Guard medium polar icebreaker. The ship the Coast Guard intends to purchase and modify is Aiviq, a U.S.-registered ship that was originally built to serve as an Arctic oil-exploration support ship, and which has an icebreaking capability sufficient for the ship to serve following modification as a Coast Guard medium polar icebreaker. The Coast Guard’s proposed FY2025 budget requests no procurement funding for the CAPI program. The Coast Guard’s FY2025 Unfunded Priorities List (UPL) includes an item for $25.0 million in procurement funding for the ship.

Great Lakes icebreaker (GLIB). The Coast Guard’s FY2024 budget initiated a program for procuring a new Great Lakes icebreaker (GLIB) that would have capabilities similar to those of Mackinaw, the Coast Guard’s existing heavy GLIB. The FY2024 DHS Appropriations Act (Division C of H.R. 2882/P.L. 118-47 of March 23, 2024) provided $20.0 million in procurement funding for the GLIB program. The Coast Guard’s proposed FY2025 budget requests no procurement funding for the program. The Coast Guard’s FY2025 UPL includes an item for $25.0 million in procurement funding for the program.

Below is a Fincantieri news release reporting steel has been cut for the first of a new class of Offshore Patrol Vessels for the Italian Navy.

Unlike the US, France, and the UK, Italy has no overseas territories. Their Exclusive Economic Zone is less than 1/22 the size of that of that of the US or France. Even so, they have 13 ships they classify as Offshore Patrol Vessels. Three of them are large at over 5,800 tons full load. (Seven more of these are planned.) In most navies they would be classified as frigates. The other ten are very different, about 1500 tons full load, and 80 (262′) to 89 meters (291′) in length, displacing about 300 tons less than a WMEC270.

Global data reports, “These four new OPVs will replace numerous warships still in service; some, such as the Lerici-class minehunters, have been in use for nearly 40 years…” There are twelve Lerici class, divided into two groups. The first four were commissioned in 1985, about seven years earlier than the remaining eight. Two of the first four were placed in reserve in 2012. Are the minehunters being used as patrol vessels or will the new ships have a minehunting capability? It is not clear if the new OPVs have provision for a stern ramp or for containerized mission modules.

The new ships are 2,400 tons full load and about 95 meters (312′), in length overall, so about 60% larger than what we might see as their existing medium endurance OPVs. Army Recognition’s Navy News reports that the new class is “equipped with a CODLAD (Combined Diesel-electric and Diesel) propulsion system, enabling speeds over 24 knots, with a range of 3,500 nautical miles at 14 knots.”

The range is short by US Coast Guard standards, but Italian vessels don’t have the long transits US Coast Guard cutters have going to Alaska, the Eastern Pacific drug transit zone, or to the Western Pacific, and it might not be that bad after all. The Coast Guard gets a lot of long distance work out of the 154 foot fast response cutters that have a range of only 2,500 miles. 3500 miles at 14 knots suggests a 5,000 mile range at ten knots. A CODLAD power plant means these ships are likely to be very fuel efficient at slow speeds.

These ships, like the much larger Thaon di Revel class will have an “Integrated Naval Cockpit” in which the pilot and copilot (I think that means Officer of the Decky and Quartermaster of the Watch) have seated positions from which to control helm, throttles, and other systems including some forms of radar, navigation, communications and combat system functions. The captain will have a similar position behind the pilot and copilot.

Notably, this class is being built by Fincantieri, owner of Fincantieri Marinette Marine which is currently building the new Constellation class FFGs for the Navy. They also built the Freedom class LCSs, the Juniper class WLBs, the Keeper class WLMs, and USCGC Mackinaw.

Fincantieri: works start on the first next-generation Offshore Patrol Vessel for the Italian Navy

24 September 2024

The steel cutting ceremony for the first of four next-generation Offshore Patrol Vessels (OPVs) that Fincantieri will build for the Italian Navy took place today at the Riva Trigoso shipyard (Genoa).

The ceremony was attended, among others, by the General Manager of Fincantieri’s Naval Vessels Division, Dario Deste, the Director of the Naval Armaments Directorate – NAVARM, Admiral Chief Inspector Giuseppe Abbamonte, and the CEO of Orizzonte Sistemi Navali, Giovanni Sorrentino.

This program, put in place to contribute to the modernization and renewal of the Italian Navy’s units, envisages the construction of four vessels, with an option for additional two, with the first delivery scheduled for 2027. The overall value of the first four ships, contracted by Orizzonte Sistemi Navali (OSN), a joint venture owned by Fincantieri (51%) and Leonardo (49%), is approximately 1.2 billion euros, including the related logistical support.

The OPV program responds to the need to ensure adequate capabilities for presence and surveillance, maritime patrolling, merchant traffic control, protection of lines of communication and the exclusive economic zone, as well as operations to protect against threats derived from marine pollution, such as toxic liquid spills.

With a length of about 95 meters long, a displacement of 2,400 tons and the capacity to accommodate 97 crew members on board, these new patrol vessels will be marked by a package of technological solutions, as well as standards of excellence in automation and maneuverability, that will make them suitable for operating in a wide range of tactical scenarios and weather conditions.

Among the most innovative features is the integrated naval cockpit, developed for the Italian Navy’s Multipurpose Offshore Patrol Vessels (PPAs), co-produced by Fincantieri NexTech and Leonardo. This represents a generational leap, allowing the control of engines, rudders, and platform systems, as well as some combat system functions, by just two operators – pilot and co-pilot – thus optimizing efficiency and safety.

The OPV program marks a major achievement for Fincantieri, further strengthening its position as a global leader in naval defense with its FCX product range, which includes these new patrol vessels. This project not only reinforces the company’s strategic role as a partner of the Italian Navy, but also deepens its collaboration with Leonardo through Orizzonte Sistemi Navali, showcasing Italy’s expertise in defense and in advanced naval integration.

Defense News reports on the progress, or lack of progress, on the European SeaSpider anti-torpedo torpedo.

I think my post “What Does It Take to Sink a Ship” may have been quoted,

“Torpedoes have historically been one of the main threats to surface vessels, with the weapon involved in more than half of sinkings of U.S. Navy ships during World War II, according to U.S. Coast Guard data cited by Dutch researchers at TNO, a government-linked research organization.”

My summary data on 92 sinkings of major US Navy surface warships during WWII was,

• 38 by torpedoes alone (41.3%)
• 16 by suicide planes (17.4%)
• 12 Bombs alone (13%)
• 11 by gunfire alone (12%)
• 6 by torpedoes and gunfire (6.5%)
• 5 by mines (5.4%)
• 4 by torpedoes and bombs (4.3%)
• 1 by bombs finished off by gunfire (1.1%)

As can be seen, torpedoes were involved in 48 of the 92 sinkings (52%).

With so little apparent progress on the European system I wonder if they are waiting to see if the Very Light Weight Torpedo, also called the Compact Rapid Attack Weapon (CRAW), will be successful as an anti-torpedo torpedo.

Unfortunately, I have not heard anything about the CRAW since early 2023 when Raytheon was awarded a contract to build 18 prototypes for use on submarines.

Naval News reports Indonesia is completing two new 321 foot Offshore Patrol Vessels that are equipped like light frigates,

The Indonesian Navy (TNI AL) witnessed the launch of two of its future offshore patrol vessels (OPVs)…The first vessel, KRI Raja Haji Fisabilillah (391), was launched on September 18, while the second ship, KRI Lukas Rumkorem (392), followed on September 20….the two identical OPVs have a length of 98 metres and a width of 13.5 metres. The ships are capable of reaching a maximum speed of 28 knots, with a cruising speed of 20 knots.

“TNI AL revealed that both OPVs would be armed with Leonardo 76mm and 40mm guns, Escribano 20mm guns, Roketsan 2×4 Surface to Surface Missile Launcher System, and torpedo launchers.” (I added link found in this quote–Chuck)

These ships look like a Damen design, but there is no indication that is the case, and it doesn’t correspond to any of Damen’s designs. Indonesia has two classes of Damen designed warships, four corvettes and two light frigates, that may have influenced the design.

Wikipedia reports the ships are powered by four diesel engines. These are the same type of 7,280 kW (9,760 hp) MTU/Fairbanks Morse 16V28/33D STC diesel engines used in the Offshore Patrol Cutter (OPC). The Indonesian OPVs use four engines while the OPC uses only two.

Significantly the anti-ship cruise missiles are from Turkey rather than China, a previous supplier.

The Naval News report also indicates that Indonesia has also recently acquired two 149 foot vessels similar to the Fast Response Cutters (pictured above).

“…on September 5, the service welcomed two new PC-40-class patrol boats, KRI Butana (878) and KRI Selar (879) …Armed with MSI-DS Seahawk LW30M guns (the 30mm Mk38 Mod4 in US service–Chuck), the two PC-40 vessels…are 45.5 metres long and 7.9 metres wide. They can achieve a maximum speed of 24 knots and a cruising speed of 17 knots…each with a crew of 35…”

Military.com has published a post that includes pay charts along with supplemental information. You can find it here.

Naval News reports, “Japan Coast Guard will build the biggest patrol vessel in its history.”

To call this ship a “patrol ship” is misleading. It is unarmed. I don’t expect it to do much patrolling. At 199 meters (673′) in length and displacing 30,000 gross tons, it would be very uneconomical.

It will be more like a mobile base for response to high profile incidents including war, natural disaster, or major public events.

The US has no direct counterpart, but there are parallels in the National Security Multi-Mission Vessels (NSMMV) which will serve as training ships for the five State Maritime Academies (SMA) but are also expected to be available to respond to Natural Disasters. There are also similarities to the Expeditionary Sea Base program.

Does the US Coast Guard need a comparable capability? If so, we might look at adapting the NSMMV, small crew, part time training ship for the CG academy, part time mother ship for distant operations, ready for disaster response.
