WASHINGTON: The Air and Space Forces are speeding efforts to adopt 3D printing as a major pillar of force sustainment, now making critical spare parts for weapon systems such as engine components for fighters and rockets.
“Additive and advanced manufacturing [has] been going like gangbusters across the Air Force and Space Force — printing thousands of parts for airplanes,” Air Force acquisition head Will Roper said yesterday. “We're starting to print parts for satellites, including propulsion.”
And today, the Air Force Rapid Sustainability Office (RSO) announced that it had reached a first milestone in its collaboration with General Electric to 3D print metal engine parts for aircraft — printing a metal sump pump for F-110 engines used by both F-15 and F-16 fighter jets. According to the announcement, the next phase of the program — Phase 1B , now being planned — will involve a family of parts on the TF34 engine, which has been in service for more than 40 years.
“The collaborative effort between the US Air Force and GE shows great promise toward the adoption of metal 3D printed parts as an option to solve the US Air Force's current and future sustainment challenges,” Col. Benjamin Boehm, director of propulsion at the Air Force Life Cycle Management Center (AFLCMC) said in a press release. “This capability provides an alternate method to source parts for legacy propulsion systems throughout their life cycle, especially when faced with a diminishing supplier base or when infrequent demands or low volume orders are not attractive to traditional manufacturers.”
GE originally approached the Air Force with the idea of a collaboration on 3D printed parts in 2019, and in April this year the service brought in the Defense Logistics Agency to help certify the GE-made parts for airworthiness.
ALCMC, as we reported way back in September at the Air Force Association shindig, has also been pushing to get its depots around the country certified to print their own spare parts, beginning with those not critical to life and death. Air Force leaders see additive manufacturing as key to resolving the service's serious problems in maintaining aging aircraft and infrastructure and lowering costs.
That said, the new 3D sump pump cover is an important piece of the engine.
“Compared to other parts on the F110 engine, the sump cover might have lower functionality, but is incredibly important. It needs to be durable, form a seal and it needs to work for the entire engine to function – which is of course critical on a single engine aircraft like the F-16,” said James Bonar, engineering manager at GE Additive.
The RSO-GE program is using a spiral development model, increasing the complexity and scale of parts printing with each phase. “In this program, complexity involves moving from simpler part identification, progressing to part and family of parts consolidation and eventually tackling complex components and systems, such as common core heat exchangers,” the press release said.
Roper told reporters yesterday in a Zoom briefing that due to the COVID-19 pandemic, RSO has transformed its planned Advanced Manufacturing Olympics, originally planned to coincide with the now-postponed Tokyo Summer Olympics in late July, to a virtual event to be held November. It will allow 3D printing companies to show off their wares to potential service customers via a number of challenges, including a “printer shoot-off” and a “Box of Parts” challenge where manufacturers will compete to create a drone part without a blueprint.
“We have been growing our network of small batch makers across the Air Force and Space Force,” Roper said. “I've been so passionate about bringing in additive manufacturing, and small batch digital manufacturing, to help on aircraft parts availability.”
The COVID-19 crises has proven the “additive” value of tapping into a network of small manufacturers as the Air Force has scrambled to obtain personal protective equipment for airmen at far-flung bases, he explained. Because many large producers of items like face masks are overwhelmed, the service set up the “Air Force Rapid Advanced Manufacturing Portal,” or “AFRAMP,” as a method of finding and vetting small producers to meet service needs.
“It's a portal where small batch manufacturers can make their capabilities known — show what they're able to produce — we vet them, and that then allows these small companies in aggregate to add up to large batch manufacturing,” Roper said. “We've already delivered over 11,000, different PPE devices to seven air bases that wouldn't have otherwise been able to get access for personal protective gear.”
His hope is to expand that portal to other types of advanced manufacturing in the future.
“I'm excited about scaling it up beyond just personal protective gear, and really having it be a one-stop-shop in the government for companies that can make things in small quantity — that can't mass produce, but can produce in mass if they're added up with a lot of their other sister companies.”

By: Andrew Chuter LONDON — The British government has confirmed it is developing a new nuclear warhead for its missile submarines, days after the U.S. revealed the program was going ahead before Parliament had been informed. In a written statement to Parliament, Defence Secretary Ben Wallace confirmed Feb. 25 that Britain is working on a new warhead to equip it's Trident missile-armed nuclear submarine fleet. “To ensure the Government maintains an effective deterrent throughout the commission of the Dreadnought Class ballistic missile submarine we are replacing our existing nuclear warhead to respond to future threats and the security environment,” Wallace said. The announcement was not expected to be made prior to publication of the defense, security and foreign policy review scheduled for late this year. But the Conservative government's hand was forced when U.S. officials revealed last week the program was up and running. That caused a stir in the U.K., as high-profile programs like the nuclear deterrent are usually announced in Parliament first. It's only a courtesy, but if Parliament is not informed first, ministers can be forced to attend the House of Commons to make a statement. “The decision is basically a forgone conclusion, but the announcement has come sooner than expected. We were looking at probably next year but certainly not before the defense and security review due for release towards the end of the year,” said David Cullen , the director at the U.K.-based Nuclear Information Service, an independent organization promoting awareness of nuclear weapons issues. Adm. Charles Richard, commander of U.S. Strategic Command, and Alan Shaffer, the Pentagon's deputy undersecretary of defense for acquisition and sustainment, separately made statements that Britain is pursuing development of its own version of the W93 warhead, which is in the assessment phase for the U.S. military ahead of replacing U.S. Navy W76 warhead. “It's wonderful that the U.K. is working on a new warhead at the same time, and I think we will have discussions and be able to share technologies,” Shaffer told an audience at the Nuclear Deterrence Summit, hosted in Washington by ExchangeMonitor. Shaffer said the W93 and the British weapon “will be two independent development systems.” Richard, in testimony prepared for the Senate Armed Services Committee, said Feb. 20 that the W93 will “support a parallel replacement warhead program in the United Kingdom.” Wallace told Parliament that the Defence Ministry's “Defence Nuclear Organisation is working with the Atomic Weapons Establishment: to build the highly skilled teams and put in place the facilities and capabilities needed to deliver the replacement warhead; whilst also sustaining the current warhead until it is withdrawn from service. We will continue to work closely with the US to ensure our warhead remains compatible with the Trident.” The new British warhead will replace the existing weapon, known as the Trident Holbrook, which equips the four Vanguard-class submarines charged with providing Britain's nuclear deterrence capability. Cullen noted that the existing British weapon is unlikely to be very different from America's W76. “They are both fitted to the same Trident missile used by Britain and the U.S. Our assumption is the two warheads are very close, if not virtually identical," he said. The Atomic Weapons Establishment in the U.K. is undertaking a life-extension program on its stock of warheads, including replacing some electronics and systems to improve accuracy and provide performance benefits. The Trident Holbrook entered service along with the Vanguard-class submarines in the mid-1990s. Britain plans to replace the subs in the early 2030s with four new Dreadnought-class subs. Work on the £31 billion (U.S. $40 billion) boat program is already underway. Britain is also spending billions of pounds building infrastructure to support the Atomic Weapons Establishment's development, building and testing of a new warhead at sites in southern England and Valduc, France, where Britain is cooperating in hydrodynamic experiments with the French Alternative Energies and Atomic Energy Commission as part of a wider nuclear agreement. Cullen said there is little in the public domain on the delivery timetable for the current warhead updates. “They started delivery of the life-extended warheads around 2016/2017. The warheads will last up to another 30 years if you assume they are doing similar changes to updates being undertaken by the U.S.,” he said. “I expect Mk4A, [as the updated weapon is referred to], to come out of service in the mid-2040s with the replacement warhead being available from the late 2030s at the earliest.” Britain and the U.S. have cooperated on nuclear weapons development for decades. In 1958, they signed what is known as the Mutual Defence Agreement to formalize that arrangement. That pact remains in place and is renewed about every decade. It was last signed in 2014. https://www.defensenews.com/global/europe/2020/02/25/britain-confirms-new-nuclear-warhead-project-after-us-officials-spill-the-beans/
