Defense Department study calls for cutting 2 of the US Navy’s aircraft carriers
By: David B. Larter
WASHINGTON – An internal Office of the Secretary of Defense assessment calls for the Navy to cut two aircraft carriers from its fleet, freeze the large surface combatant fleet of destroyers and cruisers around current levels and add dozens of unmanned or lightly manned ships to the inventory, according to documents obtained by Defense News.
The study calls for a fleet of nine carriers, down from the current fleet of 11, and for 65 unmanned or lightly manned surface vessels. The study calls for a surface force of between 80 and 90 large surface combatants, and an increase in the number of small surface combatants – between 55 and 70, which is substantially more than the Navy currently operates.
The assessment is part of an ongoing DoD-wide review of Navy force structure and seem to echo what Defense Secretary Mark Esper has been saying for months: the Defense Department wants to begin de-emphasizing aircraft carriers as the centerpiece of the Navy's force projection and put more emphasis on unmanned technologies that can be more easily sacrificed in a conflict and can achieve their missions more affordably.
A DoD spokesperson declined to comment on the force structure assessment.
"We will not comment on a DoD product that is pre-decisional,” said Navy Capt. Brook DeWalt.
The Navy is also working on its own force structure assessment that is slated to be closely aligned with the Marine Corps' stated desire to become more closely integrated with the Navy.
Cutting two aircraft carriers would permanently change the way the Navy approaches presence around the globe and force the service to rethink its model for projecting power across the globe, said Jerry Hendrix, a retired Navy captain and analyst with the Telemus Group.
“The deployment models we set – and we're still keeping – were developed around 15 carriers so that would all fall apart,” Hendrix said, referring to standing carrier presence requirements in the Middle East and Asia-Pacific. “This would be reintroducing reality. A move like this would signal a new pattern for the Navy's deployments that moves away from presence and moves towards surge and exercise as a model for carrier employment.”
A surge model would remove standing requirements for carriers and would mean that the regional combatant commanders would get carriers when they are available or when they are needed in an emergency.
With 9 carriers, the Navy would have between six and seven available at any given time with one in its mid-life refueling and overhaul and one or two in significant maintenance periods. The net result would be significantly fewer carrier deployments in each calendar year.
The assessment reducing the overall number of carriers also suggests that the OSD study didn't revamp the Carrier Air Wing to make it more relevant, Hendrix said.
Esper has taken a keen interest in Navy force structure, telling Defense News in March that he had directed the Pentagon's Office of Cost Assessment and Program Evaluation (CAPE), along with the Navy, to conduct a series of war games and exercises in the coming months in order to figure out the way forward toward a lighter Navy, but said any major decisions will be based around the completion of a new joint war plan for the whole department, which the secretary said should be finished this summer.
“I think once we go through this process with the future fleet — that'll really be the new foundation, the guiding post,” Esper told Defense News. “It'll give us the general direction we need to go, and I think that'll be a big game changer in terms of future fleet, for structure, for the Navy and Marine Corps team.”
When it comes to carriers, Esper said he saw a lot of value in keeping carriers in the force structure, and that it wasn't going to be an all-or-nothing decision.
“This discussion often comes down to a binary: Is it zero or 12?” Esper said. “First of all, I don't know. I think carriers are very important. I think they demonstrate American power, American prestige. They get people's attention. They are a great deterrent. They give us great capability.”
Revamped Surface Fleet
The OSD assessment also calls for essentially freezing the size of the large surface combatant fleet. There are about 90 cruisers and destroyers in the fleet: the study recommended retaining at least 80 but keeping about as many as the Navy currently operates at the high end.
The Navy's small surface combatant program is essentially the 20 littoral combat ships in commission today, with another 15 under contract, as well as the 20 next-generation frigates, which would get to the minimum number in the assessment of 55 small combatants, with the additional 15 presumably being more frigates.
The big change comes in the small unmanned or lightly manned surface combatants. In his interview with Defense News, Esper said the Navy needed to focus integrating those technologies into the fleet.
“What we have to tease out is, what does that future fleet look like?” Esper said. “I think one of the ways you get there quickly is moving toward lightly manned [ships], which over time can be unmanned.
“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.
“To me that's where we need to push. We need to push much more aggressively. That would allow us to get our numbers up quickly, and I believe that we can get to 355, if not higher, by 2030.”
The Navy is currently developing a family of unmanned surface vessels that are intended to increase the offensive punch for less money, while increasing the number of targets the Chinese military would have to locate in a fight.
That's a push that earned the endorsement of the Chief of Naval Operations Adm. Michael Gilday in comments late last year.
“I know that the future fleet has to include a mix of unmanned,” Gilday said. “We can't continue to wrap $2 billion ships around 96 missile tubes in the numbers we need to fight in a distributed way, against a potential adversary that is producing capability and platforms at a very high rate of speed. We have to change the way we are thinking.”

Space Force’s stopgap polar communications system passes another milestone
Nathan Strout The U.S. Space Force's stopgap Arctic communications system has passed another major milestone, with it's Control and Planning Segment (CAPS) ground system passing a critical design review. The Space and Missile Systems Center said officials completed a “delta critical design review” of Enhanced Polar System Recapitalization's (EPS-R) CAPS design June 25. In a press release, SMC noted the assessment included three months of review by the government and contractor teams, covering areas of risk, software and hardware requirement traceability, testing, performance, cost and schedule. Slated to launch in late 2022, the EPS-R payloads will fill a vital gap in providing secure communications for war fighters in the Arctic. The constellation it's replacing, the Enhanced Polar System (EPS) is not expected to last until the polar components of the Protected Tactical SATCOM and Evolved Strategic SATCOM are fielded in the 2030s, and so EPS-R will serve as a stopgap measure in the interim. Both EPS-R and EPS are effectively the Arctic components of the Advanced Extremely High Frequency constellation. Northrop Grumman was awarded a $429 million contract for the two EPS-R payloads in February 2018. The payloads will be hosted on two Space Norway satellites. The EPS-R payloads passed critical design review in October. Northrop Grumman was also awarded an $87 million contract in May 2019 to design and build the Control and Planning Segment (CAPS) which will manage both the EPS-R and EPS payloads. “The EPS-R program's unprecedented approach provides an advantage to warfighters in the increasingly contested Arctic region. EPS-R leverages the best practices of our industry partners, in concert with commercial space and launch vehicle providers while collaborating with our Norwegian partners. The EPS-R CAPS system will command the EPS/EPS-R constellation allowing US Space Force space operators to provide continuous communication services to Arctic users,” explained Maj. Craig Zinck, EPS-R Ground program manager, in a statement. EPS-R CAPS will now move to further testing. https://www.c4isrnet.com/battlefield-tech/space/2020/07/09/space-forces-stopgap-polar-communications-system-passes-another-milestone/

Boeing and Mitsubishi sign agreement to support Japan F-15 upgrades
By: Mike Yeo   1 day ago MELBOURNE, Australia — American firm Boeing has signed an agreement with Japanese company Mitsubishi Heavy Industries to support upgrades to Japan's fleet of F-15 fighter jets. The agreement, made through the U.S. Direct Commercial Sales process, is part of a larger $4.5 billion modernization program for 98 of Japan's F-15J/DJ Eagle interceptors ordered through the U.S. Foreign Military Sales process and approved by the U.S. State Department in 2019. Boeing will provide MHI with retrofit drawings, ground support equipment and technical publications for the upgrade of the first two F-15J aircraft to the Japan Super Interceptor configuration, also known as F-15JSI. The full suite of upgrades will introduce a new radar, electronic warfare capabilities and weapons. Also included is a new advanced cockpit system running on an advanced mission computer for meant to improve pilot situational awareness. The new active electronically scanned array radar will be the Raytheon AN/APG-82(v)1 multimode set, which is also being fit on the U.S. Air Force's F-15E Strike Eagles. Japan had requested 103 radars, including six spare sets, along with 116 Honeywell Advanced Display Core Processor II mission computers and 101 BAE Systems AN/ALQ-239 digital electronic warfare systems. The upgrade package will also include anti-spoofing GPS gear for more precise navigation, as well as new radios. Japan's also requested “aircraft and munition integration and test support.” The U.S. Defense Security Cooperation Agency notification about Japan's request did not provide more details, but Boeing's announcement of the contract included artwork of an F-15 in Japanese markings with a Lockheed Martin AGM-158 Joint Air-to-Surface Standoff Missile on its centerline weapon station. Japan had confirmed in its Mid-Term Defense Plan in late 2018 that it intended to procure the JASSM for long-range land-attack missions and integrate it onto F-15s. However, it's not clear whether Japan will take up Boeing's proposal to increase the number of AIM-120 medium-range air-to-air missiles that can be carried by the F-15 to 18, which the company had previously displayed on model at an aerospace exhibition in Japan. The Japan Air Self-Defense Force operates a fleet of about 200 single-seat F-15J and two-seat F-15DJ Eagle aircraft. These are all configured for an air defense role with virtually no air-to-ground capability, and they serve with seven different operational squadrons throughout Japan, a training squadron and another unit in the dedicated aggressor role, acting as the adversary during training exercises. The fleet, particularly the two squadrons based on Japan's southern island of Okinawa, have been heavily engaged in monitoring foreign military aircraft entering Japan's air defense identification zone in the international airspace around Japan. The Defense Ministry says these foreign aircraft are predominantly Chinese, with Russian aircraft coming in at a distant second. The Japan Times newspaper recently reported on China's increased use of an air base in its Fujian province to fly fighter jets near the disputed Senkaku islands. In response, the Japan Air Self-Defense Force scrambles interceptors from Okinawa once the Chinese jets take off from the Fujian base. The newspaper also reported that the Japan Air Self-Defense Force is scrambling four instead of two aircraft on each occasion, noting that the Chinese base is closer to the disputed islands than the Japanese air bases in Okinawa. https://www.defensenews.com/industry/2020/07/29/boeing-and-mitsubishi-ink-deal-to-support-japan-f-15-upgrades/
