Production of one of the F-35′s most anticipated bombs has been on hold for almost a year
By: Valerie Insinna
WASHINGTON — Deliveries of a new precision-guided bomb under development by Raytheon for the F-35 and other fighter jets have been at a standstill for about a year as the company struggles to correct a technical problem involving a key component.
A fix for the issue, which brought production of the Small Diameter Bomb II to a halt in July 2019, could be approved by the government as soon as July, said Air Force spokesman Capt. Jake Bailey in response to questions by Defense News.
However, a June report by the Government Accountability Office pointed out that continued technical issues have already caused a delay in fielding the munition, with Raytheon forced to redesign a key component and retrofit all 598 bombs already delivered to the Air Force and Navy.
The Small Diameter Bomb II — also known as the GBU-53 StormBreaker — was designed with a tri-mode seeker that includes a millimeter wave radar, imaging infrared and semi-active laser that allow the weapon to engage targets in all weather conditions and environments where visibility is obscured by dust and debris.
The Air Force and Navy plan to integrate SDB II with a range of fighter aircraft including the F-15, F/A-18 Super Hornet and F-35 joint strike fighter, but the munition has been mired in development for more than a decade.
This latest stoppage in production was prompted by internal audits by Raytheon, which found that the clips used to hold the bomb's fins in place “suffered vibration fatigue over long flight hours,” Bailey said. The clips serve “as the backup fin storage device” used to keep the fins in place in case other components fail, noted Bailey, who added that there have been no incidents during tests involving the SDB II fins inadvertently deploying.
However, the GAO wrote that the premature deployment of the fins, which help guide the bomb in flight, could damage the weapon as well as cause a safety hazard for the aircraft carrying it.
“While this problem could affect all aircraft carrying the bomb, officials said the greatest impact is to the F-35, because the bomb is carried in the aircraft's internal weapons bay and could cause serious damage if the fins deploy while the bomb is in the bay,” the GAO stated.
Raytheon declined to comment on this story, directing questions to the Air Force.
Raytheon plans on mitigating the issue with a newly designed clip that reduces the vibration of the fins, and will completely pay for developing the fix and retrofitting it on the bombs that have already been delivered, the GAO said. The Air Force confirmed that testing of the new device has already been completed and is going through final reviews.
But while Raytheon and the Air Force had hoped to restart production in April, travel restrictions caused by the ongoing global COVID-19 pandemic contributed to further delays. The government now hopes to approve the fix in July, after which production will restart and the retrofit process for existing bombs will begin.
“The fin clip failure is the sole reason production was partially halted; once final government approval is obtained, ‘all up round' production can resume,” Bailey said, using a phrase that describes a fully assembled weapon. The Air Force estimates that retrofits will be completed by August, as Raytheon's supplier has already begun manufacturing the replacement component, which are easily installed on the outside of the weapon.
“Until production resumes, the total Lot 3 deliveries remain at 204 of the 312 assets on contract,” Bailey said.
All this puts initial operational capability at least a year later than the service's original timeline, which predicted IOC would occur in September 2019. The Air Force declined to name a current estimate for when IOC would be achieved, but said it would happen after a separate milestone known as the “initial fielding decision,” which involves the approval of the head of Air Combat Command and is set for the third quarter of 2020.
The issue with SDB II's fins is just one of several technical problems with which Raytheon is grappling. The program completed operational tests in 2019, but hardware and software changes are needed after 11 failures were reported. Two hardware fixes have already been put in place, and eight failures were related to software problems that will be addressed in future updates, the GAO said.
The sole outstanding issue involves an anomaly with SDB II's guidance system. Fixing it could require Raytheon to redesign the component and conduct retrofits on all bombs already delivered, according to GAO.
A review board of the problem is in the “final stages of analysis,” Bailey said. The Air Force and Raytheon plan to establish whether a replacement component is necessary no later than June 30.
Although the weapon has not even been officially fielded, some components are already becoming obsolete. A Raytheon subcontractor that makes circuit cards used in the guidance system is expected to stop producing those components years sooner than anticipated.
As a result, that the Defense Department may have to order all circuit cards needed for the program of record before December, according to the GAO.
That timeline has now been extended to January 2022, “which provides ample time for program office action before the new deadline,” Bailey said.
Despite the bomb's ongoing problems, Raytheon continues to rake in contracts for the program. In February, the Defense Department awarded a $15 million increase to a previous SDB II contract for additional technical support. In September, the company received a $200 million contract for lifecycle support during the bomb's engineering and manufacturing development phase.
According to a Raytheon news release, the Navy recently completed the first guided release of SDB II from a F/A-18E/F Super Hornet.

UK: Modernising Defence Programme - Update
Defence Secretary Gavin Williamson has provided a final update on the Modernising Defence Programme to the House of Commons. In July, I made a statement setting out headline conclusions from six months of work on the Modernising Defence Programme (MDP). Since then, work has continued apace. Firstly, I would like to welcome the extra £1.8 billion of funding for Defence, including the additional £1 billion that was in last month's Budget. Today, I want to provide an update on the MDP, and set out the work that will be ongoing. I have placed a full report on the MDP in the library of the House. First, I should put the MDP into context. The 2015 Strategic Defence and Security Review was the right plan for Defence at that time. The Government put the Defence budget on a firmer footing, increasing throughout the life of the Parliament. Defence is much stronger as a result of that. NATO is growing in strength and the UK is a leader. More allies are meeting the 2 per cent spending guideline, or have developed plans to do so. We are the second largest defence spender in NATO, one of only a small number of allies to spend 2 per cent of our GDP on defence, and invest 20 per cent of that in upgrading equipment. We can be proud of what we have achieved since 2015. But we have to also be vigilant. National security challenges have become more complex, intertwined and dangerous since 2015 and these threats are moving much faster than anticipated. Persistent, aggressive state competition now characterises the international security context. In response to the growing threats the MDP was launched in January. And, in the last year, our Armed Forces have demonstrated their growing capability, engaged globally, and supported the prosperity of the UK. The Royal Navy has increased its mass and points of presence around the world. We have taken steps to forward base the Army, enhancing our global posture. The Royal Air Force has continued to innovate, and has celebrated a proud past its RAF100 years since its creation. Progress has also made in cyber and space, as the changing character of warfare makes both domains increasingly important. We have reinforced the UK's position as a leading voice in NATO and on European security. And, our Armed Forces have led the way for Global Britain, tackling our adversaries abroad to protect our security at home and nurturing enduring relationships with our allies and partners. Through the work over the past year the MDP has identified three broad priorities, supported by the additional £1.8 billion invested in Defence. Firstly, we will mobilise, making more of what we already have to make our current force more lethal and better able to protect our security. The UK already has a world-leading array of capabilities. We will make the most effective use of them. We will improve the readiness and availability of a range of key Defence platforms: major warships, attack submarines, helicopters and a range of ISTAR platforms. We are adjusting our overseas training and deployments to increase our global points of presence, better to support allies and influence adversaries. To improve the combat effectiveness of our Force, we will re-prioritise the current Defence programme to increase weapon stockpiles. And we are accelerating work to assure the resilience of our Defence systems and capabilities. We can mobilise a full spectrum of military, economic and soft power capabilities. And, where necessary and appropriate we will make sure we are able to act independently. We will also enhance efforts with our allies and partners, aligning our plans more closely with them, acting as part of combined formations, developing combined capabilities, and burden-sharing. And we continue to invest in, and grow, our global network of Defence personnel and the education and training we offer in the UK and overseas. Secondly, we will modernise, embracing new technologies to assure our competitive edge Our adversaries and competitors are accelerating the development of new capabilities and strategies. We must keep pace, and conceive of our joint force as consisting of five domains, air, land, sea, cyber and space, rather than the traditional three. We must modernise, targeting priority areas. A major new step will involve improved Joint Forces Command that will be in a better position so that defence can play a major role in preventing conflict in the future and improve our cyber operations and capabilities across the armed forces but also across government as well. This year Defence's Innovation Fund put £20 million towards projects in areas including unmanned air systems, virtual reality training, and enhanced digital communications for the Future Commando Force. The fund will grow to £50 million next financial year, increasing the scope, ambition and value of the projects it can support. We will launch new ‘Spearhead' innovation programmes that will apply cutting-edge technologies to areas including sub-surface threats to our submarines, our intelligence, surveillance and reconnaissance capability, and command and control in the Land Environment as well. And to drive innovation and change through the Department I am launching a Transformation Fund. Next year, I will ring-fence £160 million of MOD's budget to create this fund available for innovative new military capabilities. I will look to make a further £340 million available as part of the Spending Review. This fund will be available for new innovative military capabilities which allows us to stay one step ahead of our adversaries. Together these and other steps will enable the acceleration of our modernisation plans. Thirdly, we will transform, radically changing the way we do business in Defence. We need to improve markedly the way we run Defence. To sustain strategic advantage in a fast-changing world, we must be able and capable of continuous and timely adaptation. We will embrace modern business practices and establish a culture that nurtures transformation and innovation. We also need to create financial headroom for modernisation. Based on our work to date, we expect to achieve over the next decade the very demanding efficiency targets we were set in 2015, including through investment in a programme of digital transformation. We will develop a comprehensive strategy to improve recruitment and retention of talent, better reflecting the expectations of the modern workforce. We will access more effectively the talents of our ‘Whole Force' across all three Services, Regulars, Reserves, Civil Service and industrial partners. Looking ahead, dealing effectively with persistent conflict and competition will increasingly hinge on smarter, better informed long-range strategy. To help achieve these goals we will establish a permanent Net Assessment Unit, as well as a Defence Policy Board of external experts, to bring challenge to Defence policy and to Defence strategy. Our achievements under the MDP have made Defence stronger. The capability investments and policy approaches set out, with the £1.8 billion worth of Defence funding, will help us keep on track to deliver the right UK Defence for the challenging decade ahead. Without a shadow of a doubt, there is more work to be done as we move towards next year's Spending Review. We must sustain this momentum if we are to realise our long-term goals of increasing the lethality, reach and mass of our Armed Forces. I will do everything within my power to make sure that the UK remains a Tier-One military power in the decade ahead, and that we continue to deliver the strong defence and security that has been the hallmark of the government. I commend this statement to the House. The Modernising Defence Programme https://www.gov.uk/government/speeches/modernising-defence-programme-update
