The Pentagon is eyeing a 500-ship Navy, documents reveal

and

WASHINGTON — The Pentagon's upcoming recommendation for a future Navy is expected to call for a significant increase in the number of ships, with officials discussing a fleet as large as 530 hulls, according to documents obtained by Defense News.

Supporting documents to the forthcoming Future Navy Force Study reviewed by Defense News show the Navy moving towards a lighter force with many more ships but fewer aircraft carriers and large surface combatants. Instead, the fleet would include more small surface combatants, unmanned ships and submarines and an expanded logistics force.

Two groups commissioned by Secretary of Defense Mark Esper to design what a future Navy should look like suggested fleets of anywhere from 480 to 534 ships, when manned and unmanned platforms are accounted for — at least a 35 percent increase in fleet size from the current target of 355 manned ships by 2030.

The numbers all come from an April draft of inputs to the Future Navy Force Study conducted by the Office of the Secretary of Defense. While the number will likely have changed somewhat in final recommendations recently sent to Esper, the plans being discussed in April are notable as they reflect what will likely be major shift in the Navy's future — and the expectation is that a larger-than-planned Navy based on the concepts laid out in the documents will remain intact in the final analysis.

Esper himself hinted at that in comments last week. In a speech delivered at the think tank Rand, the secretary called for a Navy of “over 350 ships,” specifically by increasing the Navy's shipbuilding funding account.

“In short, it will be a balanced force of over 350 ships — both manned and unmanned — and will be built in a relevant time frame and budget-informed manner,” he said.

Indeed, the fleet compositions presented in the inputs broadly reflect the concept of a lighter fleet more reliant on unmanned or lightly crewed vessels that Esper described to Defense News in a February interview.

“One of the ways you get [to a larger fleet] quickly is moving toward lightly manned [ships], which over time can be unmanned,” Esper said then. “We can go with lightly manned ships, get them out there. You can build them so they're optionally manned and then, depending on the scenario or the technology, at some point in time they can go unmanned.”

The Future Naval Force Study, overseen by Deputy Secretary of Defense David Norquist, kicked off in January after Esper decided he wanted an outside take on the Navy's self-review of its future force structure. The OSD-led review tasked three groups to provide their version of an ideal fleet construction for the year 2045, one each by the Pentagon's Cost Assessment & Program Evaluation office, the Joint Staff, the Navy and a group from the Hudson Institute.

Those fleets were war-gamed and the results were compiled into the Future Naval Force Study, which was briefed to Esper earlier this month. Ultimately, the Navy is using the feedback from the study to create their shipbuilding plan and fiscal 2022 budget request, the service said in a statement.

“The Future Naval Force Study is a collaborative OSD, Joint Staff and Department of the Navy effort to assess future naval force structure options and inform future naval force structure decisions and the 30-year shipbuilding plan,” said Navy spokesman Lt. Tim Pietrack. “Although COVID-19 has delayed some portions of the study, the effort remains on track to be complete in late 2020 and provide analytic insights in time to inform Program Budget Review 22.”

The April documents viewed by Defense News included notional fleets designed by CAPE and the Hudson Institute. Defense News did not have access to the Navy's inputs into the FNFS. Neither fleet reviewed by Defense News, nor the fleet developed by the Navy, will be the final composition reflected in the FNFS. The numbers, however, provide a glimpse of the radically different future fleet likely to be reflected in the final analysis expected later this year.

    General Atomics’ New Compact, High-Powered Lasers

    GA is building a prototype 300-kW missile defense laser for the Pentagon and a 250-kW airborne version with Boeing. By SYDNEY J. FREEDBERG JR.on December 09, 2020 at 3:04 PM WASHINGTON: General Atomics is so confident in a unique technology they say solves the heat and weight problems found in rival laser designs that they're making it the core of two distinctly different projects. The Office of the Secretary of Defense is funding General Atomics and two competitors to build experimental lasers able to blast out some 300 kilowatts of power – enough to burn cruise missiles out of the sky. This project is about scaling up laser power output and testing alternative technologies for the services to pick up for separate follow-on programs. Meanwhile, Boeing and General Atomics are jointly developing a smaller laser weapon – starting at about 100 kilowatts but capable of growing to 250 kW. Unlike OSD's, this 250 kW weapon is being built at the companies' own expense, essentially on spec. (The technical term is IRAD, Independent Research And Development). Like OSD, Boeing and GA are hoping to demonstrate technology that'll be picked up by the services for a wide range of ground- and ship-based applications: The company says they're targeting the Army's Stryker-mounted M-SHORAD and its larger truck-borne IFPC, as well as Navy shipborne models. But for the pilot project, they've set themselves a very specific and demanding technical challenge: make their laser fit aboard an airplane – and make it fire accurately from that plane in flight. (Breaking D readers will remember the Airborne Laser, a huge chemical laser on a modified 747, as well as plans to arm the Next Generation Air Dominance planes with lasers.) Call in the “New York, New York” school of engineering: If you can make your laser work on a plane, you can make it work anywhere. “The idea is, if we can do it for an aircraft, then it truly could be able to go on any ground or sea platform,” said GA's VP for lasers, Michael Perry. “An aircraft...has the largest constraints on size, weight, and power.” Now, that doesn't mean getting lasers to work on ships or Army vehicles is easy. In some ways, surface platforms have a harder time: Their lasers have to penetrate the thickest, most moisture-laden layers of the atmosphere. And, Perry told me, while an aircraft in flight is constantly vibrating, you can account for that with sophisticated beam control software and high-quality aiming mirrors: That tech is tricky to build, but not bulky to install once you've built it. By contrast, a laser installed on a surface platform has to handle sudden, massive jolts as the warship crashes over a wave or the truck drives over a ditch, and that requires shock absorption systems, which are bulky and heavy. (While General Atomics and Boeing haven't said what aircraft they're planning to test the laser aboard, given the fact that Perry thinks extensive shock-absorption will be unnecessary, that suggests it isn't going to be a fighter jet or anything that makes violent high-gee maneuvers. That's in line with Air Force Special Operations Command's longstanding interest in putting a laser cannon aboard their AC-130 turboprop gunship). So GA's major focus in this project seems to be proving how compact their technology can be. Smaller size is a big advantage of the GA approach, Perry said, which they refer to as scalable distributed gain. Fibers, Slabs, & Distributed Gain What is a “distributed gain” laser, anyway? In the Wild West days of Reagan's Star Wars program, the Pentagon looked into lots of ways of powering lasers, from literal nuclear explosions – an idea called Project Excalibur – to massive vats of toxic chemicals, like the ones that filled the converted Boeing 747 that became the Airborne Laser. The real progress, however, has come with so-called solid state lasers: They pump light into a crystalline “gain medium,” which then amplifies the power of that light (hence “gain”), until it's released as a laser beam. But there are two main ways of building a solid-state laser: A slab laser, as its name implies, uses a single big chunk of crystal as the gain medium. This gives you a single coherent beam of laser light. The problem with slab lasers is heat buildup. The bigger you make the slab, the further the distance from its core to the edges, which means it takes longer to disperse waste heat, which can build up and damage the system. (You may recognize this from high school physics as a manifestation of the square-cube law). So slab lasers tend to require cooling systems, which are bulky and heavy. A fiber laser, by contrast, uses lots and lots of fiber-optic cables as gain media. Each individual fiber is very thin, and you can leave space between them, so it's easy for them to disperse waste heat. The problem with fiber lasers is the act of combining the beams. The bigger you make the laser, the more fibers you need – a 250-kW weapon might take 100 fibers, Perry said – and each fiber produces its own, weak laser beam, which you then have to combine into a single, powerful beam. Beam combination systems tend to be expensive and complex, not to mention (surprise!) bulky and heavy. General Atomics' distributed gain laser tries to strike a balance. Instead of a single big slab, you have several smaller slabs, each of them thin enough to disperse heat quickly. But instead of each of these slabs producing its own beam in parallel, which you then have to combine, you connect them in serial. The initial light source goes into the first slab, which magnifies it and shoots it into the second slab, which magnifies it still more. In theory you could have a third slab as well, even a fourth and fifth, though that's not what GA is building here. (They don't have to be lined up end to end, because you can use high-quality mirrors to bounce the light around a corner). “It is a series of slabs,” Perry told me. “The single beam passes through them all, as opposed to being separate lasers.” The advantage of distributed gain for high-power lasers is that you need neither the extensive cooling systems of a slab laser, nor the exquisite beam-combination systems of a fiber laser. “It's pretty compact,” Perry told me. “If you came out to see if you would be surprised at how short it is.” That said, there is a minimum length for a given amount of power output. That's why General Atomics couldn't fit the same 300-kW weapon they're building for OSD onto Boeing's aircraft (again, they're not saying what that aircraft is), which is why that version had to be scaled down to 250 inches. “The problem we have is, the 300-kw architecture is about 18 inches longer then the 250,” Perry said ruefully. “Believe it or not, as painful as it is and as frustrated as I am, I cannot eke out another 18 inches of length... The platform can't even give us another 12 inches.” It may be frustrating for Perry and his team to build two different versions of their lasers, rather than build two identical copies of the same thing – but the exercise could help prove to potential customers just how adaptable the basic design can be. https://breakingdefense.com/2020/12/general-atomics-new-compact-high-powered-lasers/

    UK F-35s Clear IOC For Land-Based Ops; UK Spending Big on Defense

    By PAUL MCLEARY WASHINGTON: The UK is ready to start deploying the first batch of its new F-35 fighter overseas the country's top defense official said Thursday, while introducing a slew of new cruise and attack missiles for its Typhoon jets. The announcement of Initial Operational Capability (IOC) for nine F-35Bs comes weeks after the Royal Navy performed its first F-35 landings aboard the new Queen Elizabeth-class of aircraft carrier, built specifically to accommodate the F-35B. The head of Lockheed Martin UK, Peter Ruddock, noted that the IOC pertains to “land-based aircraft.” That seems sensible given that Joint Strike Fighter operations from the carrier just began. But questions surround the overall health of the UK's military, as it embarks on an expansive modernization program that is facing brisk headwinds in the form of an uncertain withdrawal from the European Union and looming budget shortfalls in the coming years. On Thursday however, Defence Secretary Gavin Williamson stood in front of a hangar full of F-35s and Typhoons at the RAF Marham air base, which has just undergone a major facelift to accommodate the F-35 — including new runways and a training center — to declare a new era in UK power projection. “The incredible F-35 jets are ready for operations, a transformed Typhoon has the power to dominate the skies into the 2040s and we continue to look even further into an ambitious future,” he said. “The RAF has long shown Britain at its great and global best, and today it lifts our nation to even greater heights.” Alongside the F-35 were Typhoon jets, soon to be equipped with a slew of new capabilities developed under the three-year, $540 million Project Centurion. Chief among them is the Storm Shadow air-to-ground cruise missile which boasts a range of 350 miles, the precision guided air-to-air Meteor missile with a 62-mile range, and the air-to-ground Brimstone precision attack missile. All of the missiles are made by Paris-based defense firm MBDA, a joint venture between European defense leaders Airbus, BAE Systems, and Leonardo. Air Marshal Sir Stephen Hillier, chief of the Air Staff, added: “The successful integration of Storm Shadow, Brimstone and Meteor on Typhoon completes and enhances the transition of world-class capabilities” from the retiring Tornado jets, which will “offer a step-change in our ability to employ air power around the world.” After the HMS Queen Elizabeth makes its first deployment in 2021, it will be followed two years later by the HMS Prince of Wales, bringing to a close a gap in carrier capability that Britain has experienced since retirement of the Invincible and Ark Royal. Royal Navy officials have said they're eager to get back into carrier operations, which will allow the UK to project power with fifth generation aircraft across the Middle East, Pacific, and in the Arctic, which is emerging as a major flash point as Russia and China rush to push assets north. The deployments will come as a welcome relief for the US Navy, which is struggling with maintenance on its own 11-carrier fleet. The American ships have been strained over the past 17 years of war in the Middle East and growing tensions with China in the Pacific. But the uncertainties over Brexit hangs over all of these plans. “Our nation is moving into a new era outside the EU, and our huge achievements in air capability make our commitment to a role on the world stage clear to both our allies and our enemies,” Williamson said. The UK's Director for Strategic Planning Will Jessett told reporters in Washington earlier this week that the MoD's ability to pump money into new defense programs will be affected by any deal reached between Britain and the rest of Europe, since their defense industries are intertwined. “Amongst the reasons we started to face this affordability delta in 2017 were because exchange rates did fall, relative to where they were in 2015,” he said. If we get a [Brexit] deal that's OK, I can imagine, personally, exchange rates not just stabilizing but somewhat improving. If not, it is by definition going to add further pressure into this.” He hastened to add, however, “that's not what we're planning for at the moment.” In November, the UK's National Audit Office estimated that the Ministry of Defense's defense plans will exceed allocated budgets by an average of 3.7 percent over the coming decade, which would lead to shortfalls of between $8 billion and $18 billion over that timeframe. https://breakingdefense.com/2019/01/uk-f-35s-clear-ioc-for-land-based-ops-uk-spending-big-on-defense
