Senate defense bill limits Air Force’s aircraft retirement plans
By: Valerie Insinna
WASHINGTON — The Senate Armed Services Committee wants to give the Air Force more F-35 fighter jets and drones, but the panel's version of the 2021 defense policy bill leaves many questions open about the future of the service's legacy aircraft.
In the Air Force's fiscal 2021 budget request, the service proposed retiring a number of its B-1 bombers, A-10 Warthog attack planes, RQ-4 Global Hawk surveillance drones, KC-135 and KC-10 tankers, and C-130H planes. Air Force leaders said the reductions were necessary to free up money needed for key investments in future technology areas like space and joint all-domain command and control.
However, the proposed version of the FY21 National Defense Authorization Act passed by the Senate Armed Services Committee on June 10 puts some limits on those proposed cuts. Instead of mandating the Air Force to retain a certain number of specific types of aircraft, SASC's defense bill “establishes a minimum number of aircraft for each major mission area ... and prohibits the divestment of aircraft until the minima are reached to ensure that Air Force can meet [National Defense Strategy] and combatant command requirements,” SASC said in a summary of the bill.
But with only a summary of the bill available, it's unclear how that compares with the Air Force's planned inventory reductions and whether any retirements will be permitted at all.
According to a committee staffer, the numbers proposed by SASC include a “primary mission aircraft inventory” of 1,182 fighters, 190 drones, 92 bombers, 412 tankers, 230 tactical airlift platforms, 235 strategic airlift platforms, 84 intelligence, surveillance and reconnaissance aircraft, and 106 combat search-and-rescue aircraft.
Specifically, the bill blocks the retirement of three A-10 Warthog squadrons, limits F-15C divestment, and delays the retirements of KC-10 and KC-135 tankers until after the KC-46's technical challenges are resolved. The Air Force had planned to retire 13 KC-135s and 16 KC-10s in FY21.
The summary of the bill makes it clear the SASC is concerned that the Air Force's plan to trade existing aircraft for future capabilities could lead to a drop in near-term readiness as well as an scenario where legacy aircraft are never actually replaced.
The bill “requires the Secretary of Defense to submit an annual aviation procurement plan across all services,” the summary stated. It includes language that cements the Air Force's aspiration to field 386 combat squadrons as a requirement, although one staffer clarified that the provision is more a goal than a mandate, and that there is no timeline associated with it.
SASC's legislation is far from set in stone. The bill will move to the Senate floor for debate, but its House counterpart is working on its own version of the defense authorization bill, and both chambers will have to agree on a final bill.
Where's the money going?
The House and Senate Armed Services committees make funding recommendations, which are then used by congressional budgeteers in the appropriations committees to draw up the final funding bills. Nonetheless, SASC made a number of key funding authorizations that could mean major increases for certain aircraft programs.
- Unsurprisingly, it recommended a major increase for Lockheed Martin's F-35 Joint Strike Fighter program, approving the purchase of 60 F-35A conventional-takeoff-and-landing models, 12 F-35B short-takeoff-and-vertical-landing variants, and 23 F-35C carrier-takeoff-and-landing aircraft. That's a net increase of 16 aircraft: 12 F-35As, two F-35Bs and two F-35Cs.
- General Atomics was another major beneficiary of the legislation. SASC authorized $165 million for additional MQ-1 Predator drones for the Army and $170.6 million for MQ-9 Reaper drones for the Air Force, which will keep the production line going ahead of a replacement program.
- It adds an extra $128 million for additional XQ-58 Valkyrie drones from Kratos. The Valkyrie is a low-cost combat drone currently being tested by the Air Force as part of the Low Cost Attritable Aircraft Technology effort, which seeks a “loyal wingman” aircraft that can penetrate contested environments and take on more risk than manned planes. The committee also calls for an LCAAT operational test plan and utility evaluation.
- It fully funded the Air Force's KC-46 tanker program and B-21 bomber program, according to SASC Chairman Jim Inhofe, R-Okla.
- The bill also “increases funding for critical capabilities that will help the United States maintain air superiority in contested environments, including Systems of Systems Technology Integration Tool Chain for Heterogeneous Electronic Systems (STITCHES) and advanced air-to-air weapons”

SpaceX could fill the US military’s Arctic communications gap by the end of this year
Nathan Strout The U.S. Defense Department relies on a mixture of military and commercial satellites to connect its war fighters all over the world. And while users can complain that terminals are too bulky or that they should have the roaming capability exhibited in commercial cellphone technology, the system largely works. But that's not the case in the Arctic. “Very simple things become hard when you're in the Arctic, not the least of which is communication. When you are above about 65 degrees north, satellite communication starts to diminish, and above about 70 degrees north it becomes extremely limited except for some of our more exquisite capability — submarines, for example,” said U.S. Northern Command spokesman Maj. Mark Lazane. The U.S. Space Force's primary communications satellite system, Wideband Global SATCOM, is designed to provide connectivity between 70 degrees north and 65 degrees south — basically to the edge of the polar region. The Space Force also operates two Enhanced Polar System satellites — the Arctic complement to the Advanced Extremely High Frequency constellation. EPS satellites provide highly secure, anti-jamming signals, and like its counterpart, EPS is built for high-priority military communications, like that used with submarines. And while elsewhere in the world the military supplements its purpose-built systems with commercial communications satellites, that option is limited in the Arctic. After all, commercial satellites providing coverage of other areas aren't solely serving the military, and the services rely on commercial consumers to offset the costs of designing, building, launching and maintaining a satellite. But there's far less commercial demand for satellite communications in the Arctic than in more populated areas, and commercial satellite coverage reflects that. That leaves U.S. Northern Command with a significant gap in the connections available to its war fighters and platforms. “Connection capabilities [in the Arctic] are limited and lack resiliency. We're challenged in areas from basic point-to-point connections to communication with our distributed sensors,” Lazane said. “Having a reliable broadband communications capability for Arctic operations is the top unfunded priority of USNORTHCOM. With the increase of great power competition in the Arctic, there is a need for additional communications capability and capacity.” But the command thinks it's found a solution in the form of new, proliferated commercial constellations. Private companies OneWeb and SpaceX have launched hundreds of satellites into low-Earth orbit in an effort to provide competitive broadband to users all around the world. USNORTHCOM is asking Congress for $130 million to explore OneWeb's and SpaceX's capabilities in order to provide reliable and potentially cost-effective connectivity to Arctic platforms, installations and war fighters. “Leveraging emerging proliferated low-Earth orbit commercial SATCOM providers in the Arctic enables the United States (and our allies) the opportunity to scale communications capability and capacity quickly in a cost-effective manner,” Lazane said. “The unique capabilities provided by PLEO [proliferated low-Earth orbit] commercial SATCOM providers in the Arctic enables access to high-bandwidth, low-latency communications capability and capacity.” In a Feb.11 letter to Congress, USNORTHCOM Commander Gen. Terrence O'Shaughnessy said that funding for this effort was his No. 1 unfunded priority. If approved, the $130 million in funding will be used for polar communications experiments as well as the fielding of prototype terminals that can connect to commercial PLEO constellations. If those experiments prove successful, USNORTHCOM would need another $110 million in fiscal 2022 for full coverage. SpaceX has stated that its Starlink constellation will begin offering broadband services this year, and USNORTHCOM is hopeful that could enable early Arctic capability by the end of the year. https://www.c4isrnet.com/smr/frozen-pathways/2020/05/11/spacex-could-fill-the-us-militarys-arctic-communications-gap-by-the-end-of-this-year/
