The Gepard class frigate, used by the Vietnamese navy, has a standard displacement of 1,500 tons, which increases to 1,930 tons when fully loaded. The frigate’s overall length is 102.14 meters, with a waterline length of 93.5 meters, a beam of 13.09 meters, and a draught of 5.3 meters.

It is powered by a two-shaft Combined Diesel Or Gas (CODOG) system, which includes two gas turbines, each producing 29,300 shp (21,800 kW), and a Type 61D Diesel engine generating 8,000 bhp (6,000 kW), along with three 600 kW diesel alternator sets. This propulsion system enables the frigate to reach a top speed of 28 knots.

The Gepard class frigate has a range of 4,000 nautical miles at a cruising speed of 10 knots and can sustain operations for up to 15 days. It is manned by a crew of 98 personnel.

The frigate is equipped with various sensors and processing systems, including a navigation radar of an unspecified type, Cross Dome surface and air search radar, Pop Group SA-N-4 fire control radar, Bass Stand cruise missile target designator, and Bass Tilt AK-630 fire-control system. For underwater detection, it utilizes medium-frequency hull-mounted and towed variable depth sonar.

In terms of electronic warfare and decoy capabilities, the Guepard class frigate is equipped with two Bell Shroud passive intercept systems, two Bell Squat jammers, and four 16-barreled Pk-16 countermeasure rocket launchers.

Service members from the United States, Philippines, Japan and the Republic of Korea, along with observers from the U.K., began training exercise KAMANDAG 7 on Nov. 9 to improve multinational military readiness, partnership and mutual capabilities. The bilateral KAMANDAG exercise has occurred annually since 2016.

At yesterday’s ASEAN Defence Ministers’ Meeting-Plus in Jakarta, U.S. Defense Secretary Lloyd Austin told Philippine defense chief Gilberto Teodoro that the U.S. “stands shoulder to shoulder … in defending its sovereign rights and jurisdiction in its exclusive economic zone.”

“The exercise, scheduled from November 9 to 20, will be conducted at various training sites throughout Luzon, Batanes, Zamboanga, Tawi-Tawi, and Palawan. During KAMANDAG 7, approximately 950 members of the Armed Forces of the Philippines and 850 U.S. Marines from across I and III Marine Expeditionary Forces will train alongside the Japanese Ground Self-Defense Force and the Republic of Korea Marines,” reads a statement from the Marines. “The United Kingdom Armed Forces will bring observers to KAMANDAG 7. Participation from the JGSDF, the Republic of Korea, and observers from the U.K. in this year’s iteration underscores the global importance of maritime security, demonstrating our combined commitment to maintaining stability and peace across the Indo-Pacific region.”

Marine Rotational Force Southeast Asia, headquartered at Marine Corps Base Camp Pendleton, CA, will lead the Marine Corps’ participation in KAMANDAG 7.

In the Gulf of Oman

The Dwight D. Eisenhower Carrier Strike Group is operating in the Gulf of Oman near the Strait of Hormuz.

USS Dwight D. Eisenhower (CVN-69) deployed on Oct. 14, while several of the carrier’s escorts left on Oct. 13. The carrier transited the Strait of Gibraltar on Oct 28. and transited the Suez Canal on Nov. 4.

U.S. Central Command said that an Ohio-class submarine arrived in its area of responsibility. The submarine was later confirmed as USS Florida (SSG-728). These SSGNs carry up to 154 Tomahawk Land Attack Missiles.

On Nov. 8, Houthi rebels shot down a U.S. MQ-9 Reaper off the coast of Yemen over the Red Sea, a defense official confirmed to USNI News. The defense official did not give additional details on the MQ-9 or potential recovery efforts. The Air Force has long used Reapers for surveillance and strike missions in the region.

Earlier in October, USS Carney (DDG-64) shot down a number of Houthi-launched missiles and drones that were headed in the direction of Israel. But the Pentagon could not confirm the targets, USNI News previously reported.

The DoD attributes the attacks to Iran-backed or Iranian proxy groups. The Pentagon said they are not connected to the Israel-Hamas war, although the strikes against U.S. forces started 10 days after Hamas invaded Israel and killed 1,400 Israelis, while kidnapping 240 more. In retaliation, Israel has invaded Gaza to eliminate Hamas.

According to DoD, “U.S. Military forces conducted precision strikes on Nov 12 on facilities in eastern Syria used by Iran’s Islamic Revolutionary Guard Corps (IRGC) and Iran-affiliated groups in response to continued attacks against U.S. personnel in Iraq and Syria. The strikes were conducted against a training facility and a safe house near the cities of Abu Kamal and Mayadin, respectively.”

Destroyer USS Thomas Hudner (DDG-116), operating in the Middle East, shot down a Yemeni drone in the Red Sea on Wednesday, the Pentagon said in a statement.

“On Nov. 15th and while transiting the international waters of the Red Sea, the crew of the USS Thomas Hudner (DDG 116) engaged a drone that originated from Yemen and was heading in the direction of the ship,” reported USNI News.
“Hudner‘s crew engaged and shot down the drone to ensure the safety of U.S. personnel. There were no U.S. casualties or any damage to the ship.”

Hudner is operating in U.S. Central Command, disaggregated from the Gerald R. Ford Carrier Strike Group. As of Monday, USS Gerald R. Ford (CVN-78) was operating in the Eastern Mediterranean Sea, which is under U.S. European Command rather than U.S. Central Command.

The Ford Carrier Strike Group is part of the ongoing naval buildup in the region since Hamas launched attacks in southern Israel last month. Defense Department officials say there has been an increase in the number of attacks on U.S. troops operating throughout the region since last month.

While the uptick in strikes began on Oct. 17, 10 days after Hamas launched an attack on Israel and Israel began its subsequent bombardment of the Gaza Strip, the Pentagon maintains the conflict has not expanded beyond Israel and Gaza. Israeli forces have also exchanged fire with Hezbollah in Lebanon, while the West Bank has seen an uptick in settler violence.

The Bataan Amphibious Ready Group is in the Red Sea. Bataan and Carter Hall, with elements of the 26th Marine Expeditionary Unit embarked, are in the northern Red Sea as part of the U.S. naval buildup in the region.

Bataan and Carter Hall entered the Red Sea from the Gulf of Aden on Friday, Oct. 27, according to ship spotters. The 26th Marine Expeditionary Unit is embarked across Bataan, Carter Hall and Mesa Verde.

Among many missions for which Marines are trained is evacuating civilians in conflict zones. USNI News visited the unit in April during an exercise Non-combatant Evacuation Operation (NEO) in North Carolina.

Embarked units include Amphibious Squadron 8, 26th MEU (SOC), Fleet Surgical Team 8, Tactical Air Control Squadron 21, Helicopter Sea Combat Squadron 26, Assault Craft Unit 2, Assault Craft Unit 4, and Beach Master Unit 2. The 26th MEU (SOC), based at Camp Lejeune, N.C., includes Battalion Landing Team 1st Battalion, 6th Marines; Marine Medium Tiltrotor Squadron 162 (Reinforced) and Combat Logistics Battalion 22.

 ARLINGTON, Va. — The U.S. Navy is pushing new technology to its undersea fleet to make it safer, smarter and deadlier, while also nearing a major step in developing its next-generation attack submarine.

Among the changes that will have the most impact is moving the Submarine Warfare Federated Tactical System to a cloud-based common computing environment. SWFTS comprises a sub’s sonar, imaging, electronic warfare and combat systems, and also ties into ship control, navigation and more.

Capt. Todd Weeks, the program executive officer for undersea warfare systems, said at the Naval Submarine League’s annual symposium that this move forces the decoupling of hardware and software, which makes it quicker and easier to upgrade each.

The common computing system also comes with boosted cybersecurity and creates the bandwidth to install artificial intelligence tools for submariners.

Weeks said submariners are inundated with more sonar and electronic warfare data than they can manually analyze. An AI tool could rapidly toss out meaningless data, allowing sailors to look through a narrower set of potentially interesting information.

As the Navy begins to test these AI tools onboard submarines, it built a so-called sandbox for these applications so users can access the data generated by SWFTS without posing a risk or otherwise affecting existing systems. The Navy can experiment with apps in this sandbox before committing to their installation with SWFTS.

Weeks said the current SWFTS build has a small sandbox, which will increase in size in the coming years so multiple apps can simultaneously undergo testing.

Next-gen attack sub

The Navy intends to begin buying its SSN(X) attack submarine about a decade from now, following what would be a 35-year run building the Virginia-class boats.

Rear Adm. Jon Rucker, the program executive officer for attack submarines, said his team is conducting technology development and early design work. They’ll incorporate the best of the Virginia, Seawolf and Columbia submarine designs and focus on four attributes: speed, payload capacity, stealth and operational availability — minimizing time needed for major depot work and maximizing the time it can be out on patrol.

Rucker said Nov. 7 at the same conference that Navy leadership signed the SSN(X) initial capabilities document, which is now with the Joint Staff for final signatures and approvals.

The Navy will then begin an analysis of alternatives in 2024, he said, noting this process will help decide how to proceed — a clean-sheet design, modifying the existing Virginia-class design, or something in between.

Torpedoes and countermeasures

For the ships and aircraft that hunt enemy submarines, Weeks’ office is offering greater capability by developing an advanced sonar array for existing Mk 54 lightweight torpedoes. His team is also creating an advanced lightweight torpedo to leverage new sonar technology and add “significant improvement in lethality and speed and depth so that there’s no submarine in the world that is safe from our [anti-submarine warfare] forces.”

To supplement the torpedo inventory, Weeks said in his Nov. 8 speech, his office is also “in the process of developing” the Compact Rapid Attack Weapon, or CRAW, a spinoff of the anti-torpedo torpedo defensive system the Navy uses on aircraft carriers.

Weeks told reporters the Penn State University’s Applied Research Laboratory developed CRAW, which features a new warhead and fresh operational software compared to the old system. The Navy is working with several industry partners, who he declined to name, to put the system into production. He expects to sign off on its Milestone B achievement in the coming weeks, he added.

CRAW will first deploy for an offensive anti-submarine mission, and then receive a defensive anti-torpedo torpedo capability via a software update.

Weeks said CRAW will arm Virginia submarines “soon” and that the aviation and surface communities are interested in the system, which is smaller than the lightweight torpedo but has less range.

Safety gear

Vice Adm. William Houston, the commander of Naval Submarine Forces, said Nov. 7 he’s made rapid safety improvements on the Ohio-class ballistic missile and guided-missile submarines, including improved firefighting gear.

Previously, sailors would rely on hand-held thermal imagers to find their way around dark, smoky areas of the sub during an emergency. But the Ohio boats would typically only have two of these onboard, leaving many first responders unable to see how close they were to a fire.

In a few months, the Navy developed and purchased a new self-contained breathing apparatus that has a thermal imaging heads-up display built into the face mask. Now, every first responder could have thermal imaging without having to find or hold a device.

The entire Ohio class has this new apparatus, and the Virginia attack subs will get it soon, Houston said.

Warspite bombarding defensive positions off Normandy, 6 June 1944. Note the non-operational X (upper rear) turret.

Completed during the First World War in 1915, she was assigned to the Grand Fleet and participated in the Battle of Jutland. Other than that battle, and the inconclusive Action of 19 August, her service during the war generally consisted of routine patrols and training in the North Sea. During the interwar period the ship was deployed in the Atlantic Ocean and the Mediterranean Sea, often serving as flagship, and was thoroughly modernised in the mid-1930s.

During the Second World War, Warspite was involved in the Norwegian Campaign in early 1940 and was transferred to the Mediterranean later that year where the ship participated in fleet actions against the Royal Italian Navy (Regia Marina) while also escorting convoys and bombarding Italian troops ashore. She was damaged by German aircraft during the Battle of Crete in mid-1941 and required six months of repairs in the United States. They were completed after the start of the Pacific War in December and the ship sailed across the Pacific to join the Eastern Fleet in the Indian Ocean in early 1942. Warspite returned home in mid-1943 to conduct naval gunfire support as part of Force H during the Italian campaign. She was badly damaged by German radio-controlled glider bombs during the landings at Salerno and spent most of the next year under repair. The ship bombarded German positions during the Normandy landings and on Walcheren Island in 1944, despite not being fully repaired. These actions earned her the most battle honours ever awarded to an individual ship in the Royal Navy. For this and other reasons, Warspite gained the nickname the “Grand Old Lady” after a comment made by Admiral Sir Andrew Cunningham in 1943 while she was his flagship.

When she was launched in 1913 the use of oil as fuel and untried 15-inch guns were revolutionary concepts in the naval arms race between Britain and Germany, a considerable risk for Winston Churchill, then First Lord of the Admiralty, and Admiral of the Fleet Sir Jackie Fisher, who had advocated the design. However, the new “fast battleships” proved to be an outstanding success during the First World War. Decommissioned in 1945, Warspite ran aground under tow to be scrapped in 1947 on rocks near Prussia Cove, Cornwall, and was eventually broken up nearby.

Warspite was the sixth Royal Navy ship to bear the name. It likely originated from an archaic word for woodpecker, ‘speight’; with the implication that, during the age of sail the war-speight would peck holes in her enemies’ wooden hulls.

WASHINGTON — For more than a decade, the US Navy has considered the former Enterprise (CVN-65) no longer operational. In fact, since 2018, the 1,101-foot behemoth has been mostly floating pier side in Newport News, Va., awaiting final dismantlement and disposal.

Ships come and go in the Navy, but their disposal is not usually such a prolonged and complicated affair. They can be used as target practice for what the Navy calls a “SINKEX” or handed over to scrapping and salvaging companies, among other options.

But for a host of reasons, those routes are non-starters for the service’s first nuclear-powered aircraft carrier. Instead, after studying the problem for years, the service has finally settled on a path forward: enlisting commercial industry for a job it has historically done itself, and likely creating a new norm for how all nuclear-powered carriers will be disposed of going forward.

To lead that charge, Breaking Defense has learned the Navy has set up a new office just to focus on the inactivation and disposal of nuclear-powered aircraft carriers. While a spokesman declined to comment on the status of the new office, the Navy believes its decision will save millions of dollars, years of man-hours in labor and crucially, precious dock space at the public shipyards.

Whatever the service ends up doing, both analysts and the Navy have said it will likely set precedents for future carriers facing disposal, and the clock is ticking. The longer it takes, the more likely it is the Pentagon will risk a buildup of older carriers taking up various private and public ports around the country.

Even if everything goes according to the Navy’s preliminary plans, time is not on the service’s side. Public Navy documents show that Enterprise will not begin dismantlement until 2025, and the work will continue through 2029 — meaning even if everything stays on track, the work will be ongoing when the second nuclear-powered aircraft carrier, USS Nimitz (CVN-68), is scheduled to leave the operational fleet in 2026. The USS Eisenhower (CVN-69) will follow suit not long after.

“The Navy has really had a tough time figuring out … what’s the process we’d go about dismantling this thing,” said Bryan Clark, a fellow at the Hudson Institute and retired submariner. “That’s why the Enterprise in particular has been sitting around waiting to be dismantled. And we’re going to have the same problem with the Nimitz.”

‘A Lot Easier With Submarines’

The Navy is not going into this process blind. It has decades of experience rendering nuclear-powered submarines and cruisers safe. Since 1986, the service has disposed of 142 reactor compartment packages, according to Navy spokesman Alan Baribeau.

The traditional process for disposing of a nuclear-powered sub begins with defueling the boat and towing it to Puget Sound Naval Shipyard in Bremerton, Wash., where workers cut out the section of the ship containing the propulsion plants. The spent fuel, reactors and reactor compartments are packaged and sent to various Department of Energy facilities, which specialize in long-term storage and disposal of nuclear materials, in the Pacific Northwest.

“That was a lot easier with submarines and cruisers,” said Steven Wills, an analyst at the Center for Maritime Strategy. “These [carriers] take up too much space and affect operational units that are based in Bremerton.”

Compared to modern submarines that house just one reactor, Enterprise has eight, a remnant of the early stages of nuclear technology when construction began in 1958. The Nimitz-class, which the service started building in the 1960s, has two reactors per ship. (Baribeau noted that the design differences between Enterprise, the Nimitz and Ford-class carriers will be taken into consideration when the latter classes are prepared for disposal, but added that “lessons learned” from Enterprise will inform the Navy’s choices for its successors.)

Even just finding a place to dock a carrier can be challenging. Space at one of the four public shipyards comes at a premium, which is where HII, the only American shipbuilder capable of constructing aircraft carriers, comes into play.

Following the Navy’s call in 2012 to take Enterprise out of operational service, it contracted the shipbuilding company to defuel the carrier, among a list of other tasks necessary to prepare it for dismantling, work that concluded in 2018. Still, compartments of the ship that contained nuclear materials for decades have been irradiated and would pose a risk to the environment if the service were to conduct a “SINKEX.”

Since then, the Navy’s efforts to study how to dispose of Enterprise have largely been internal. It wasn’t until 2022 that the service released its first draft of a public document, called an “environmental impact statement,” in which it laid out three possible methods for disposal: The first two methods involved Puget Sound Naval Shipyard in Washington and vary in how the reactors would be packaged and shipped off for disposal. Enlisting industry’s assistance was the third option, and the Navy made clear that was its preferred method.

In September the service ruled out disposal strategies utilizing Puget Sound in the final draft of its environmental impact statement. Although the Navy has not yet awarded a contract, the impact statement says it has evaluated potential sites in Hampton Roads, Va., Brownsville, Texas, and Mobile, Ala.

A Novel Solution To A Novel Problem

While analysts said submarines were an apt analog due to the service’s history of disposing of the boats’ nuclear reactors, the Navy has looked elsewhere for comparisons in the dismantling process of a nuclear-powered carrier.

“Notably, several civilian, land-based, nuclear power plants, which are larger and more radiologically complex than Navy aircraft carrier reactor plants, have successfully been dismantled and disposed of by the commercial nuclear services industry,” the service said in a solicitation to industry earlier this year.

Clark noted the Navy’s original nuclear propulsion programs predate the civilian nuclear energy sector, meaning it was an imperative at the time for the Pentagon to have the expertise in-house to see the technology’s lifecycle through from start to finish. But, unlike when Enterprise was being built, there are now private companies capable of dismantling nuclear power plants.

“The Navy could tap into that capacity to be able to dismantle these nuclear reactors [while they’re still onboard the carrier], and dispose of the components, instead of taking the whole reactor compartment out and then disposing of the reactor compartment like we do to submarines,” he said.

Then there’s the cost.

The service estimates that using commercial industry for virtually all aspects of the dismantlement and disposal will run it between $554 and $696 million, according to the environmental impact statement. By comparison, the two alternatives involving the public shipyards have price tags ranging from $1.1 billion to $1.4 billion. The impact statement also says the commercial option will only take five years while the public shipyards would require 15 years or more to complete the job.

However, those estimates are in fiscal year 2019 dollars and are not adjusted for inflation, meaning the true costs of dismantling Enterprise, which is slated to begin in 2025, will almost certainly be higher.

Alternatively, storing the carrier indefinitely would run the Pentagon $10 million per year, according to the impact statement. It’s not clear how much of that money accounts for renting pier space at a private shipyard such as HII’s Newport News, but it does give a glimpse into how much keeping the ship in the water is costing the Defense Department annually.

Finally, by using commercial industry, the Navy hopes it will free up space at the public shipyards, which are already overburdened with the demands of maintaining the Navy’s current fleet.

Baribeau, the Navy spokesperson, added that if the service were to use Puget Sound for the disposal work, it would require infrastructure modifications at the Port of Benton and “improvements to the transport route” used to reach the Department of Energy’s facilities “due to the heavier weight and larger size of the dual reactor compartment packages.”

The commercial route will “reduce the Navy inactive ship inventory, eliminate costs associated with maintaining the ship in a safe stowage condition, and dispose of legacy radiological and hazardous wastes in an environmentally responsible manner, while meeting the operational needs of the Navy,” Baribeau said.

“Commercial dismantlement and disposal of ex-Enterprise supports the Navy prioritizing limited public shipyard resources on active fleet maintenance while realizing cost benefits to the U.S. taxpayer,” he continued.

Bradley Martin, a researcher at the RAND Corporation, predicted the Navy’s choice to contract with industry for Enterprise’s disposal will pay off down the road.

“I think this, if it works out, it’ll actually be a good model,” he told Breaking Defense. “The capacity of Navy shipyards to deal with everything they’re supposed to be dealing with is already pretty strained.”

The dismantlement process, he added, “takes a lot of time and effort and people.”

The Legacy of Hyman Rickover

Hundreds of miles away from the former USS Enterprise, in Groton, Conn., the Navy in October commissioned one of its newest nuclear-powered, Virginia-class fast attack submarines. The boat is named after Adm. Hyman G. Rickover, a veritable legend in the submarine community who is credited with establishing the nuclear propulsion program that now powers much of the modern Navy’s fleet.

While the admiral was known for his strict adherence to safety protocols, Wills questioned to what extent the Navy in the late 1940s and 1950s, when Rickover was on active duty, had thought about what would occur when a nuclear vessel was no longer operationally useful.

Rickover “was a big proponent of reactor safety and safety within the operating process, but I’m not sure anybody ever got to the retirement process. You could probably argue that this is all catching up with us now,” Wills said.

“It was one thing to retire submarine reactors and smaller surface ship reactors, but aircraft carriers represent a bigger challenge,” he said.

Atago (愛宕) was the second vessel in the Takao-class heavy cruisers, active in World War II with the Imperial Japanese Navy (IJN). These were among the largest and most modern cruisers in the Japanese fleet, designed with the intention to form the backbone of a multipurpose long-range strike force. Her sister ships were Takao, Maya and Chōkai.^[1]

Background[edit]

The Takao-class ships were approved under the 1927 to 1931 supplementary fiscal year budget, and Atago, like her sister ships, was named after a mountain. In this case, she was named after Mount Atago, located outside Kyoto. Even though Takao was the name ship of the class, Atago was actually finished before Takao.
