The Navy's New Frigate Revealed
Well, sort of. The Pentagon's new RFP doesn't provide a whole lot of detail on what the Navy wants.

Rich Smith
"Now this is not the end. It is not even the beginning of the end. But it is, perhaps, the end of the beginning" ... of the U.S. Navy's search for a new frigate warship. (With apologies to Winston Churchill.)

Last week, at long last, the U.S. Navy issued its official Request for Proposals (RFP) from defense contractors interested in building it a new frigate. Smaller than a destroyer but larger than a coastal patrol vessel, the Navy is seeking a warship more robust than its much-maligned Littoral Combat Ship (LCS) to fill out its requirement for 52 "small surface combatants" in the fleet.

Here's what we know about it.

It takes a village to build a frigate
The Navy first released a "request for information" from defense industry participants on July 10, 2017, seeking feedback on what they could produce, how fast, and at what cost; the request called for something along the lines of a frigate to replace the Navy's now-long-departed Oliver Hazard Perry-class frigates. Over the past 16 months, the admirals have presumably been digesting this information, and on Nov. 7 they finally issued their official RFP inviting bids from the industry.

Despite the time that's passed already, the 77 pages (mostly restating the rules of government contracting) contained in this RFP only actually sketch out a few key requirements for the vessel, hereafter known as "FFG(X)":

First and foremost, we're now definitely talking about an FFG, or "guided missile frigate," so a vessel packing some real offensive missile punch. This contrasts with the existing LCS design, which lacks a dedicated missile capability.
"Aviation integration" is to be part of the design, so this frigate will carry helicopters, or at least drones.
The frigate in question is not to be designed from the keel up as a "clean sheet." Rather, defense contractors are to propose using an existing "parent design" vessel that has already "been through production and demonstrated (full scale) at sea," and modify it to suit the Navy's needs.
The modifications are to "use ... commercially available, non-developmental and proven technologies," and equipment "common" to other U.S. Navy warships whenever possible.
That sketches out the bare bones of the program -- but still leaves a lot of details floating in the water. How fast must the frigate go? How much armament must it carry? How much damage must it be able to endure? Does it have to -- and this could be key -- produce enough electrical "juice" to power newfangled weapons systems such as railguns and laser cannons?

We just don't know.

Timeline, cost, and bidders
The Navy's RFP doesn't even contain much in the way of a timeline, other than mentioning that construction should begin by 2020. Fortunately, just a couple days after the RFP came out, the Congressional Research Service published a report filling in a few more details that should interest investors.

Production of the first frigate, as the RFP stated, is to begin in 2020, followed by a second in 2021. Construction should then continue through 2030 at the rate of two ships per year, until the Navy receives a full complement of 20 warships.

Price-wise, most frigates should cost approximately $950 million apiece (the prototype can cost a little more) resulting in an overall program cost of perhaps $20 billion for the winning contractor. And only one contractor will win this contract: unlike the LCS program, frigate production will not be split between two different prime contractors.

As for who this contractor might be, production is to take place within the continental United States, a fact which suggests the prime contractor candidates will be limited to the usual suspects: Lockheed Martin (NYSE:LMT), General Dynamics (NYSE:GD), and Huntington Ingalls (NYSE:HII). That being said, the frigate may be based on a "parent design" from either domestic or foreign military shipbuilders. This raises the possibility that, whichever of the Big Three wins the prime contract, it could theoretically end up sharing its revenues with a foreign partner, which could be contributing the hull design.

Before French, British, German, and other military frigate producers get their hopes up too high, though, remember: Lockheed Martin (maker of the Freedom-class LCS), General Dynamics (Independence LCS), and Huntington Ingalls (which builds the National Security Cutter) each already has its own basic hull design in hand. Chances are good that, when bidding, they'll favor these respective "parent" designs so as to keep all the revenues to themselves.

There's always the possibility of a big foreign shipbuilder partnering with a smaller U.S. company as its prime, of course -- sort of like how Embraer partners (successfully) with Sierra Nevada to build Super Tucano fighter planes for the Pentagon, or how Airbus partnered with Northrop Grumman to bid to build the Air Force's new tanker aircraft a few years ago (unsuccessfully).

Still, if I were a betting man, I'd wouldn't put my money on a foreign competitor. When all's said and done, I expect to see Lockheed, General Dynamics, or Huntington Ingalls sail away with the win and collect the $20 billion prize at the end.

Mothballed Oliver Hazard Perry frigates will not be reactivated, US Navy decides


USS Kauffman was the last Oliver Hazard Perry-class frigate in US Navy service

The US Navy has decided not to reactivate old Oliver Hazard Perry-class frigates, according to an USNI News report which cites an internal service memo.
The main driver for the decision is likely the cost of bringing the ships – the last of which was decommissioned in 2015 – out of mothballs.
According to USNI News, the reactivation costs would be counted in the hundreds of millions.
The idea of Oliver Hazard Perry-class frigates being used for anti-trafficking missions in the US Southern Command was first proposed by US Navy secretary Richard V. Spencer. Spencer suggested the frigates could be brought back into service as a low-cost platform for basic tasks like near-shore operations and drug interdiction.

As the option has turned out to be less cost-effective than previously thought, Spencer is now suggesting the use of littoral combat ships and expeditionary fast transports for the drug trafficking roles. The internal memo quoted by USNI News reveals that the navy secretary called for at least four ships, equipped with unmanned aerial vehicles, to be deployed in support of the Joint Interagency Task Force next year.

Lockheed Martin Unveils its FFG(X) Frigate Design

At the Surface Navy Association's (SNA) 2018 National Symposium currently held near Washington DC, Lockheed Martin unveiled the design of the frigate it is proposing for the U.S. Navy FFG(X) requirement.


Lockheed Martin "Freedom-Variant" Frigate unveiled at SNA 2018

The US Department of Defense released a Request for Information (RFI) in July 2017 to let the industry know what the U.S. Navy is expecting from the Fast Frigate, Guided (Experimental) or FFG(X). The RFI says, "A competition for FFG(X) is envisioned to consider existing parent designs for a Small Surface Combatant that can be modified to accommodate the specific capability requirements prescribed by the US Navy."

The U.S. Navy wants a frigate that can keep up with carrier strike groups as well as conduct missions on its own. “The FFG(X) will normally aggregate into strike groups and Large Surface Combatant led surface action groups but also possess the ability to robustly defend itself during conduct of independent operations while connected and contributing to the fleet tactical grid.” The U.S. Navy expects the frigate to be survivable in complex scenarios: "FFG(X) will perform its missions in complex electronic warfare and anti-ship missile threat environments".



The new Frigate would likely replace the troubled, very modular, Littoral Combat Ships (LCS) for typical "frigate missions". The U.S. Navy is requesting the FFG(X) to conduct the following missions:
- Over the horizon anti-surface warfare (ASuW )
- Anti-submarine warfare (ASW)
- Independently escort logistics ship convoys
- Electronic warfare (EW)
- Electronic signals intelligence and collection (ELINT)

The frigate displacement wasn't mentioned in the RFI, but it is likely to be comprised between 4000 tons (if the design is to stay as close as possible to the LCS) and in excess of 6000 tons (in view of the requirements set by the U.S. Navy, which is particularly interested on how the shipbuilders can fit VLS for ESSM and Standard Missiles and how many).

The U.S. Navy intends to award a Detail Design and Construction contract for the first FFG(X) in 2020.

Lockheed Martin latest Frigate design is based on the Freedom-class Littoral Combat Ship (LCS). No one at Lockheed Martin was willing to discuss design details with Navy Recognition at SNA 2018, however it is our understanding that this frigate uses the 125 meters hull of an earlier design unveiled at DSEI 2017 (for comparison, the LCS measures 115 meters in length). We were told during DSEI 2017 that the crew complement of the 125m vessel was 130 sailors (compared to a crew of 65 sailors on the LCS).



The scale model unveiled at SNA 2018 features 8x anti-ship missiles fitted forward, below the bridge. Moving away from the bridge and toward the bow there 16x Mk 41 VLS cells for ESSM and/or Standard Missiles. There are also two spaces intended for Surface to Surface Missile Module (SSMM) with Longbow Hellfire missiles similar to what is fitted aboard LCS (those are intended to counter swarm attacks). The main gun is a BAE Systems Bofors Mk110 57mm as per the RFI.



Compared to the Freedom-class, the bridge and superstructre of the frigate have been completely redesigned. The bridge face is less slanted / more vertical and the superstructure forms three steps, the last one being significantly higher. This is to accommodate Raytheon's Enterprise Air Surveillance Radar (EASR). There four Nulka decoy launchers directly on top of the bridge. SEWIP electronic warfare antennas are fitted on the port and starboard sides of the main mast structure. Two larger antennas of unknown type are fitted directly above the SEWIP.



The funnels are hidden deep inside the main structure. This is likely to lower the infra-red signature of the ship. Another explanation could be that the structure was raised in order to accommodate the EASR arrays.



As we progress towards the stern of the ship, note the presence of a laser weapon system on the starboard side of the ship. There is a SeaRAM launcher on top of the helicopter hangar as per the Navy RFI.



The propulsion system remains unchanged with 4x waterjets. However we noted one last addition on the frigate's hull: the presence of bilge keels. They increase hydrodynamic resistance to rolling, making the ship roll less. Bilge keels are passive stability systems.

Lockheed Martin launched a "Frigate" page on its website for SNA 2018. Little information is provided except for this text:

With rapidly evolving threats, world markets need to confront different types of bulls and bears. That’s why Lockheed Martin is evolving its Freedom-variant ship design to confront modern threats to maritime and economic security. The Freedom-variant Frigate offers planners and commanders the strength and affordability needed to rapidly rebuild the U.S. Navy fleet and guarantee freedom of the seas for decades to come.

Lockheed partners for this project include Fincantieri Marinette Marine and Gibbs & Cox.

ARLINGTON, Va. – France is sending 350 sailors and naval aviators to deploy with a U.S. Navy aircraft carrier this spring as their nuclear-powered carrier finishes scheduled maintenance, French officials told USNI News.

The April to May deployment will occur just before France’s aircraft carrier FS Charles de Gaulle (R91) is expected to complete a major maintenance period which started in 2015. The aircrews will do carrier qualifications aboard USS George H.W. Bush (CVN-77), but the intent is to accomplish more than qualifications or cross-deck operations, Capt. Jean-Emmanuel Roux de Luze, French Naval Attaché to the U.S. told USNI News.

“We want to demonstrate our ability to integrate with U.S. military services,” Roux de Luze said. “We want to show we do maintenance, demonstrate we can load weapons.”

French Navy Dassault Rafale M fighters and Northop Grumman E-2C Hawkeye aircraft will at first fly with U.S. airwings out of Naval Air Station Oceana, in Virginia Beach. French sailors will work with their U.S. counterparts maintaining the aircraft, Rouz de Luze said. The unspecified French forces will then board Bush and operate as part of the air wing.

The agreement to send French aircraft, crews, and sailors to the U.S. was first announced in December, when U.S. Navy Chief of Naval Operations Adm. John Richardson met in Paris with his French counterpart French Navy Chief of Staff Adm. Christophe Prazuck, first reported by website Navy Recognition.

A Marine Corps CH-53E Super Stallion helicopter crashed during a routine training mission Tuesday in California, killing the four crew members aboard, the Marine Corps said.

The heavy lift helicopter was part of the 3rd Marine Aircraft Wing and was flying near El Centro, California, when the crash occurred at approximately 2:35 p.m. local time, the Marines said in a statement released early Wednesday.

“The status of all four is presumed dead pending positive identification,” the Marine Corps said. Names would be withheld pending next-of-kin notification.

Some Arty soldiers are about to get their sea legs.

Soldiers will fire Army artillery and rockets from the decks of Navy ships this summer in the largest maritime exercise in the world.

For the first time last year, Marines successfully fired High Mobility Rocket Systems from the deck of the amphibious assault ship Essex. That success was a first salvo in work to integrate fires between the two forces and find ways to use their equipment in the near-shore fight.

At that time, the Marines also asked industry to submit proposals for a mobile coastal missile defense system so that once they get ashore then can fire back to the sea.
