Moog Inc.

In December 1995, Moog acquired the servovalve product line of Ultra Hydraulics Limited, a United Kingdom based manufacturer of hydraulic components, strengthening its position in the international market. In October 1996, Moog acquired the industrial hydraulic servocontrols business of International Motion Control Inc.

By this time, Moog's business had significantly diversified, with products ranging from entertainment motion simulators, flight

controls for Commercial Aircraft, controls for communications satellites and launch vehicles as well as military aircraft programs such as the F/A-18 Super Hornet and V-22 Osprey. Government sales had dropped from 57% of total revenues to 39% of total revenues during the period 1993-1997.

In 1998, Moog acquired the Raytheon Aircraft Montek Company, located in Salt Lake City, Utah, which supplied flight

controls for commercial airplanes and regional and business jets, as well as steering controls for

tactical missiles and servovalves for both industrial and aerospace applications.

Moog expanded its industrial controls business with two further acquisitions - Hydrolux SARL, a Luxembourg manufacturer and designer of hydraulic power control systems for industrial machinery, and Microset Srl, an Italian manufacturer and designer of electronic controls for industrial machinery. Moog now claimed to be the world's market leader in industrial servovalves for a wide variety of industrial applications requiring the precise control of position, velocity and force.

By the end of the decade, Moog had more than doubled its total sales, and had also reorganised itself into three operating divisions:

Aircraft controls

Satellite and Launch Vehicle Controls

Industrial controls

2000s: Continued growth and further acquisitions

In 2000, it was announced that Moog would be working with both Boeing and Lockheed Martin on the next generation fighter aircraft for the US military, the Joint Strike Fighter program. This would ultimately become the F-35 Lightning fighter aircraft, and would be Moog's single largest ever program.

In 2004, Moog purchased Poly-Scientific from Northrop Grumman, a subsidiary specialising in slip rings, fiber optic rotary joints and motors that serve very broad markets from aviation and defence to industrial and medical. This resulted in Moog establishing a fourth business division, Components Division, alongside the existing three divisions.

In the mid-2000s, the company continued to grow, with new development programs such as the F-35 JSF and US National Missile Defense development initiative, where Moog supplied valves for the final stage kill vehicle, complemented by production programs such as the F-15 and the Hellfire tactical missile.

In 2006, the company established another new division, Medical Devices, following the acquisition of first Curlin Medical and then McKinley Medical. The division would focus on Moog's growing business supplying sensors, pumps and other components to the medical industry.

Moog closed the decade by buying GE Aviation's flight control actuation business, based in Wolverhampton in the United Kingdom. This ultimately became Moog Wolverhampton, Moog's largest business in the UK and its largest military aircraft facility outside the United States. The acquisition brought Moog contracts for the primary flight controls for the Eurofighter Typhoon, and the main engine lift system for the Rolls-Royce engine on the STOVL version of the F-35.

By the end of the decade, Moog's annual sales had grown from $630 million in 1999 to $1,849 million in 2009.

2010s: Consolidation and focus on aerospace and defense

Moog entered the 2010s still pursuing growth through with further acquisitions, diversifying its space and defense business with the purchase of two companies specialising in security and surveillance. Moog's medical devices business also expanded via acquisitions, with Moog acquiring Ethox International, a manufacturer of medical disposables and provider of microbiology, toxicology, and sterilization services and Aitecs, a Lithuania-based manufacturer of infusion therapy pumps.

By the middle of the decade, however, management had shifted strategy towards concentrating on Moog's traditional strengths in aerospace and defence, while simplifying its corporate structure. Between 2016 and 2019 Moog divested some non-core businesses within its Medical Devices, Components and Industrial divisions, eventually consolidating all three divisions back into a single Industrial Division, leaving the business with the same structure as it had in 1999, organised around three divisions - Aircraft Controls, Space and Defense Controls and Industrial Systems.

At the same time, Moog benefited from rising production rates on several long-term military and commercial aircraft programs, particularly the F-35 program which had become the largest in the firm's history. Its Space and Defense Controls division also expanded across satellites, launch vehicles, precision-guided weapons, naval systems and surveillance technologies.

2020s: Defense growth and public scrutiny

The decade began with the disruption caused by the COVID-19 pandemic, which sharply reduced demand in commercial aviation and industrial markets. Moog's sales nevertheless declined by only 1% in 2020, from $2.91 billion to $2.89 billion, as lower commercial aircraft and industrial sales were partly offset by increased demand for military aircraft and space and defense products. Its total backlog increased by 14% to $2.56 billion during the year.

In December 2020, Moog announced the acquisition of Genesys Aerosystems, based in Mineral Wells, TX, significantly boosting Moog's presence in the design and manufacture of avionics, electronic flight instrument systems and autopilot solutions.

As commercial aviation subsequently recovered, Moog also benefited from increased international defence expenditure and demand generated by growing geopolitical tensions. Production and development work included the F-35, new military aircraft programmes, missile systems, naval platforms, satellites and launch vehicles. By 2024, sales under United States Government contracts represented 38% of total company sales, while a further 9% came from foreign governments.

Pat Roche, previously President of the Industrial Division, was appointed as Chief Executive Officer in 2023. As Roche was not a United States citizen, this led to the U.S. Defense Counterintelligence and Security Agency (the “DCSA”) invalidating Moog's security clearance, which limited Moog's ability to enter into new government contracts that required facility security clearance. Moog resolved the issue by reorganizing its business, separating Aircraft Controls into distinct Military Aircraft and Commercial Aircraft divisions, with independent management structures. In this structure, Mark Graczyk, president and senior management official for Moog Military Aircraft, reported to the subsidiary's board of directors. The company thereafter reported four operating segments: Military Aircraft, Space and Defense, Commercial Aircraft and Industrial.

Between 2022 and 2025, annual sales increased from $3.04 billion to $3.86 billion. The company's growing defence business also brought increased public scrutiny. In October 2024, following a long investigation, Moog agreed a settlement of $1.7 million with the US Securities and Exchange Commission in relation to charges of breaches of the Foreign Corrupt Practices Act (FCPA).

Subsequently, following the outbreak of the Israel–Hamas war in October 2023, press coverage and campaigners drew attention to Moog components use in military aircraft and weapons systems supplied to Israel. In August 2025, four protesters staged a roof protest at Moog's Wolverhampton factory, protesting against the Moog's supply of F-35 and M-346 military aircraft components to Israel. In April 2026, M-346 shipments from Moog Wolverhampton to Israel were intercepted by Belgian customs authorities and seized, prompting a criminal investigation into alleged breaches of Belgian export and transit laws, and questions in Belgian parliament.

By the middle of the decade, Moog had become a substantially larger and more defense-dependent company, benefiting from increased military expenditure and renewed growth in commercial aviation, while facing greater scrutiny over the end use of its products and its position within global arms supply chains.

Moog at 75

In 2026, Moog marked the 75th anniversary of its founding with a year-long programme of activities under the theme "Moog at 75". The company published a series of historical articles and videos reflecting on its development since 1951, highlighting milestones in aerospace, defense, industrial automation and space exploration, while also celebrating the contributions of employees throughout its history.

Moog's primary products are electronic ambulatory infusion pumps and ambulatory enteral feeding pumps along with the necessary administration sets as well as disposable infusion pumps. Applications of these products include controlled delivery of fluids to the body, nutrition, post-operative pain management, regional anesthesia, chemotherapy and antibiotics. On January 23, 2009 Moog acquired the stock of Ethox International for $15.2 million in cash. Ethox is a medical products manufacturer and service provider based in Buffalo, New York.

On July 1, 2013, Moog announced the sale of its Buffalo operations of Ethox Medical to Dempsey Ventures. Annual sales from this division were approximately $12 million, with 88 full-time employees. Dempsey Ventures, based in Grand Rapids, Michigan, is a private equity firm focused on healthcare products. Its portfolio of companies in the anesthesia/respiratory space includes SunMed, Bay Medical and Ventlab. The Company also announced at the same time that it had engaged RBC Capital Markets LLC to assist with the strategic assessment of the remainder of its Medical Devices segment, including the possibility of divesting the entire segment.

Aircraft Parts Whistleblower Case

In 2016, Charles Shi, a former Supply Chain Manager in the Aircraft Group at Moog's Shanghai subsidiary, raised concerns about allegedly defective aircraft components and irregular supplier documentation. According to allegations subsequently summarised by a US federal court, Shi believed a Chinese supplier had used substandard manufacturing processes and concealed irregularities in parts that entered Moog's supply chain for aircraft built for the US Department of Defense. The court recorded that a Moog investigation “at least partially substantiated” Shi's concerns, although Moog disputed that the components presented a flight-safety risk. Shi alleged that he was dismissed one day after escalating his concerns directly to Moog's CEO.

The US Federal Aviation Administration subsequently investigated Shi's safety concerns and, according to Reuters, substantiated two of his allegations. One issue was closed following corrective action, while a second remained open pending the full implementation of corrective action by Boeing and verification by the FAA. Boeing and Moog said that the necessary corrective actions had been taken, while Moog maintained that the parts concerned were not flight-safety-critical and had met specification during testing.

Shi later sued Moog under the US False Claims Act, alleging that he had been dismissed in retaliation for raising concerns about aircraft parts supplied for US military programmes. In 2020, a federal court allowed his retaliation claim against Moog Inc. to proceed, finding that he had adequately pleaded the claim; this was not a finding that his allegations were ultimately proven. The litigation ended in 2021 when Shi and Moog agreed to dismiss the claims with prejudice. Publicly available reporting does not disclose the terms of any agreement or establish liability by Moog.

In November 2019, Moog announced that it had been awarded contracts for the Primary Flight Control Actuation System, the Leading Edge Flap Drive System and the Wingfold Actuation System on the F-35 fighter. The initial three year contract was worth over $400 million, approximately $135 million per annum, with production split between Moog's Wolverhampton and Elma, NY facilities.

In November 2024, Campaign Against Arms Trade cited Moog Wolverhampton Limited as one of a number of UK arms companies that was involved in the supply chain for Israel's F-35 fighter jet programme. The F-35 had been implicated in a number of airstrikes carried out in Gaza resulting in civilian casualties, in particular the Al-Mawasi airstrike which resulted in over 80 civilian casualties, of whom between 19-40 were killed.

On 2 July 2025, the United Nations Special Rapporteur on the situation of human rights in the Palestinian territories occupied since 1967, Francesca Albanese, published the report From Economy of Occupation to Economy of Genocide (A/HRC/59/23), which examined the role of corporations involved in Israel's military and security sectors. The report identified a number of major defence companies, including Lockheed Martin, Leonardo and Elbit Systems, and called on states and businesses to review their responsibilities under international law. Campaign groups opposing Moog's activities cited the report and the wider debate surrounding military supply chains as justification for continued protests at the Wolverhampton facility.

In July 2025, investigative outlets Declassified UK and The Ditch reported that Moog Aircraft Group had sent multiple shipments from its Wolverhampton facility to Hatzerim Airbase in Israel. According to the report, the consignments were addressed to the M-346 "Lavi" trainer aircraft programme, which is used by the Israeli Air Force to train pilots for frontline aircraft including the F-16 and F-35. The report noted that the UK government's September 2024 suspension of certain arms export licences to Israel did not extend to trainer aircraft, and argued that this distinction enabled continuing support for Israel's pilot training infrastructure.

Following this increased media attention, Moog worked closely with Staffordshire Police regarding security at its Wolverhampton facility. According to evidence filed in subsequent court proceedings, police officers conducted multiple visits to the site during July 2025 to review security arrangements, assess protest-related risks and advise on additional protective measures. The site was subsequently subject to regular police patrols.

On 21 August 2025, more than 700 British business leaders, founders and professionals signed an open letter organised by Business Leaders for Peace calling on the UK government to take further steps to prevent atrocities in Gaza and to uphold its obligations under international law. The initiative reflected growing engagement by figures from the business community in debates surrounding arms exports, corporate responsibility and the conflict in Gaza.

"Moog 4" Protest

On 26 August 2025, four pro-Palestinian protesters associated with Palestinian Martyrs' Justice entered Moog's Wolverhampton facility and occupied the roof of a building. Prosecutors alleged that the defendants caused damage to the site, including to roof structures and skylights. The protesters said that they had targeted the facility because of Moog's production of components for military aircraft used by Israel.

Four people were charged with criminal damage and were remanded in custody for six months before being released on bail. In September and October 2025, Moog also obtained a High Court injunction restricting protest activity at several of its United Kingdom facilities.

The first criminal trial began at Birmingham Crown Court in June 2026. On 18 June, after more than 17 hours of deliberation, the jury was unable to return verdicts on which the required majority could agree and was discharged. The Crown Prosecution Service subsequently confirmed that it would seek a retrial, which was scheduled for March 2027.

Belgian seizures and allegations of illegal military exports

In April 2026, Belgian authorities reported the interception of shipments of military-related equipment at Liège Airport that had originated in the United Kingdom and were destined for Israel. Belgian media reported that the cargo was inspected following concerns that it contained controlled military items, and that a criminal investigation had been opened to determine whether export control or transit regulations had been breached.

According to Walloon minister-president, Adrien Dolimont, “We have to see if the legislation has been respected. Here, in this case, it’s clear that it hasn’t. No transit licence was requested; if it had been, it would have been refused”.

Statements from the Belgian government and media reports identified one of the seized shipments as coming from Moog's Wolverhampton factory and bound for Israel's M-346 program. The outcome of the criminal investigation expected in August 2026.

Private Eye allegations

In May 2026, UK investigative newspaper Private Eye published allegations that, subsequent to the April 2026 seizures in Liège Airport, Moog's Wolverhampton facility continued to ship M-346 components to Israel along flight paths that overflew Belgian airspace, in apparent breach of the 16 January 2026 Royal Decree prohibiting use of Belgian airspace for any flights containing military materiel for use by the Israeli armed forces.

Private Eye alleged that Moog Wolverhampton obtained a new Open export licence from the UK Export Joint Control Unit in November 2025, which would imply that Moog's application for the licence was live at the same time as the M-346 shipments that are now under criminal investigation by the Belgian authorities.

In subsequent coverage, Private Eye also alleged that Moog Inc. was one of a number of US arms suppliers using East Midlands Airport as a transit hub for shipments of F-15 and F-16 spare parts from the US to Israel, with peaks in such shipments coinciding with peaks in Israeli air strikes against Gaza, Lebanon and Iran. The article went on to note that East Midlands Airport is majority-owned by a consortium of Greater Manchester public authorities, and therefore ultimately under the authority of the Mayor of Greater Manchester Andy Burnham.

Parliamentary discussion and civil society response

Following the Belgium seizures, a number of MPs wrote letters to the UK Government requesting clarification of its response to a British exporter breaking Belgian arms control laws, seemingly over a sustained period of time. Fleur Anderson MP and Sir Alan Campbell MP both wrote to John Healey, then Secretary of State for Defence, and Laura Trott MP wrote to Peter Kyle, Secretary of State for Business and Trade, expressing concern regarding the seizures in relation to the integrity of the UK’s export control regime, how compliance is monitored and enforced, and the importance of maintaining confidence among UK allies.

On 8 May 2026, a joint letter from Amnesty International, SaferWorld and Campaign Against Arms Trade was submitted to Liam Byrne MP, Chair of the Business and Trade Sub-Committee on Economic Security, Arms and Export Controls asking whether Moog Wolverhampton's export licences had been placed under review or suspension, and whether any assurances had been obtained from Moog that any future arms exports to Israel would be carried in full compliance with all applicable laws, including those of third countries such as Belgium.

On 9 June 2026, Campaign Against Arms Trade launched the lobbying campaign "Moog UK: Training Genocide Pilots", focusing on Moog's involvement supplying components for the F-35 programme and the Leonardo M-346 trainer aircraft used by the Israeli Air Force. The campaign argued that components for the M-346 should have been included in the United Kingdom's 2024 partial suspension of arms export licences to Israel and also raised concerns over the 2026 seizure by Belgian authorities of UK-origin military goods in transit to Israel, in relation to which Belgian officials confirmed that the original complaint concerned Moog. CAAT called for the suspension and review of relevant export licences and for an investigation into the continued export of trainer aircraft components to Israel.

On 15 June 2026, 61 British Members of Parliament and several members of the House of Lords from multiple political parties, including Baroness Sayeeda Warsi, former army officer Helen Maguire MP, Dr Simon Opher MP and Josh Babarinde MP submitted a joint letter to Peter Kyle asking the Department to clarify when it first become aware of Moog illegally shipping military components to Israel via Belgium, what communications had taken place between the Department, Moog and the Belgian authorities, and what measures, including review of export licences, it was taking to enforce compliance with legal obligations.
