GCAP

Singapore has started exploring whether to become involved in the Global Combat Air Program (GCAP), a new report suggests. While it doesn’t state that Singapore has decided to join or purchase the Tempest fighter at the center of that program, it is in line with the country’s approach to buying the F-35. At the very least, it would seem to indicate that Singapore is starting to look at the sixth-generation combat aircraft technologies that could follow the Joint Strike Fighter.

According to Janes, Singapore has begun early, informal discussions about possible participation in GCAP. These are described as exploratory, meaning Singapore is gathering information rather than negotiating membership of the program.

The report explicitly states that the Singapore government has not made any decision to become a participant in the program, which makes sense considering that the Republic of Singapore Air Force (RSAF) is still waiting to receive its first F-35s.

GCAP is a joint next-generation air combat program led by the United Kingdom, Japan, and Italy, aiming to field the Tempest sixth-generation combat jet and wider air combat system by around 2035. With the demise of the pan-European Future Combat Air System (FCAS), GCAP is the preeminent Western sixth-generation fighter effort outside of the United States.

GCAP is intended to include not only the Tempest crewed fighter but also an integrated ecosystem of AI-enabled systems, advanced sensors, networking, air-launched weapons, and autonomous ‘loyal wingman’ aircraft.

As for the RSAF, this is a notably modern and capable force, benefitting from considerable investment throughout the years.

It is currently spearheaded by a combat fleet of 40 F-15SGs, plus 49 F-16C/Ds, a combination of Block 52 and Block 52+ jets.

Next, the RSAF will receive eight conventional takeoff and landing (CTOL) F-35As and 12 short takeoff and vertical landing (STOVL) F-35B fighters. The F-35Bs will be the first to arrive, with deliveries due to start before the end of this year. These will initially be based at Ebbing Air National Guard Base in Arkansas for training, with the first F-35Bs scheduled to be stationed in Singapore from 2029.

In total, Singapore covers an area of less than 280 square miles, putting unique strains on the RSAF.

In preparation for the F-35B, the RSAF is extending the runway at Pulau Sudong, an offshore location, which will reduce the noise burden on more populated areas. The existing runway will be extended from around 6,500 feet to approximately 9,800 feet, with work to be completed by 2028. The growing demand for training capacity is something that has previously led the RSAF to look at having a detachment in Guam, but the reworked Pulau Sudong should help address the issue.

The RSAF has traditionally acquired the best available Western-made equipment to meet its combat aircraft needs. Looking at what is currently the only sixth-generation combat jet that is likely to be available to Singapore for the foreseeable future makes sense. However, as Roy Choo, a defense journalist and TWZ contributor, noted, deeper involvement in GCAP would be years away.

“From this news, it appears they may have identified a future requirement for a sixth-generation fighter, although this is unlikely to transition into a program of record for at least another two decades,” Choo explained. “As with most operators, Singapore engages with industry to stay informed about available market offerings all the time.”

In the next decade or so, the RSAF will likely remain focused on its F-35A/B program and on bringing these aircraft up to full operational capability.

Another upcoming program will be a midlife upgrade for the F-15SG, deliveries of which first began in 2008. Choo expects work on this to begin once the ongoing F-16 upgrade is finished. The F-16s are set to remain in service into the mid-2030s, according to Singapore Chief of Air Force Maj. General Kelvin Fan. The F-15SG will be around longer, giving considerable lead time for it to be replaced by a sixth-generation platform.

When it comes to a path to a potential Singapore Tempest acquisition, it is worth looking at the approach taken with the F-35.

Singapore joined the F-35 program as a Security Cooperative Participant (SCP) in 2003 when it identified the fifth-generation fighter as a potential replacement for its F-16s. At that time, Choo notes, Singapore was still receiving its F-16s and was yet to select a contender for its Next Fighter Replacement Program (NFRP) — it eventually chose the F-15SG in 2005.

Singapore placed an initial order for four F-35B in 2020, a full 17 years after joining the program as an SCP. This is very much an indication of the long-term view Singapore takes in its defense procurement.

If Singapore were to join GCAP, it would likely be part of a long-term view toward acquiring a sixth-generation fighter capability.

While Singapore has maintained generally good relations with Beijing, it is acutely aware of its economic vulnerability in the face of rising tensions in the South China Sea as China makes increasingly forceful moves to assert its claims in the region. With China preparing for potential contingencies in the South China Sea through the continued expansion of its anti-access and area-denial (A2/AD) capabilities in the region, the People’s Liberation Army Air Force — busy working on its own sixth-generation platforms — is very much the pacing threat.

Given Singapore’s prudent approach to defense procurement, it is unlikely to commit large sums of money to a program at such an early stage of development.

If pursued, a likely option would be for Singapore to join GCAP with observer status, something that Canada (another F-35 customer) recently signed up to do. “This would give greater visibility of GCAP’s governance and capabilities,” Choo added. “After all, Singapore doesn’t have the deep technological know-how as the other full-tier partners.”

“An observer status would fit with its cautious and non-committal approach to the program just as it did with the F-35 SCP membership.”

Potentially, GCAP could provide a platform for Singapore to build future relationships with other partners and secure a workshare arrangement involving supply chain and maintenance work. That would all be a long way off, however.

Logically speaking, the RSAF’s next procurement project will likely involve a collaborative combat aircraft (CCA) to build combat mass.

Interestingly, earlier this week, Singapore and Australia signed the Industrial Base Resiliency Arrangement (IBRA), which establishes a practical framework for closer defence industrial cooperation between the two nations.

The IBRA “allows both countries to engage in cross-sustainment of common defense platforms, examine priority delivery requests for defence orders, streamline equipment transfers, foster defence industry partnerships, and facilitate information exchanges to mitigate supply chain risk.”

When it comes to common defense platforms, it’s not hard to imagine that the MQ-28 Ghost Bat could be in the RSAF’s thoughts. At the same time, the F-35A and the P-8A maritime patrol aircraft will also offer commonality with Australia once they arrive in RSAF service.

Singapore has a history of studying major defense programs years before making procurement decisions. Whether it intends to buy the Tempest in the future or not, the report is the first known indication that Singapore is formally examining possible links to GCAP, and looking at sixth-generation combat aircraft more generally.

In the latest twist in Canada’s long-running saga to field a new fighter, the country’s defense minister has said that Ottawa is “interested in learning more about” the Global Combat Air Program (GCAP) next-generation fighter. GCAP is currently a trinational effort, led by the United Kingdom and involving Italy and Japan. Its centerpiece is the Tempest crewed fighter. A demonstrator for this jet is currently taking shape with BAE Systems in the United Kingdom.

David McGuinty, the Minister of National Defense of Canada, made the remarks after a meeting in Tokyo with his Japanese counterpart, Shinjiro Koizumi. Breaking Defense reports that McGuinty confirmed he had spoken with Koizumi about the GCAP, which the Canadian official described as a “promising initiative.”

“We are interested in learning more about it. I’ll take it back to my team and see what it looks ‌like,” McGuinty told Reuters.

Until now, no senior Canadian official appears to have spoken publicly about interest in GCAP. However, the development comes as Ottawa weighs up the option of a split fighter buy, which would involve acquiring the U.S.-made F-35 and one other type. This thinking has been driven by a growing rift between Ottawa and Washington.

However, the possibility of Canada coming on board GCAP as an ‘observer’ had been raised in March of this year. According to The Asahi Shimbun, a Japanese daily newspaper, unnamed Japanese officials disclosed that, during a previous meeting, McGuinty and Koizumi discussed such an arrangement.

Canada’s joining GCAP with observer status would provide it access to information on the program and could be a stepping-stone to deeper involvement.

Earlier this week, Italian Defense Minister Guido Crosetto raised the possibility of other nations joining GCAP, noting that, were that to happen, “we would be completely willing, because the more there are, the greater the chances of creating something and bringing down costs.”

Crosetto then identified Canada as “the country most interested [in GCAP] at the moment.” He said he would be “fully open” to Canada joining as an observer.

For Canada, however, GCAP would require a rethink of Canada’s potential pursuit of a split-buy approach to its new fighter.

Until now, the Saab Gripen E had been identified as the most likely candidate to be bought alongside the F-35.

Sweden has made a strong push to sell Gripen to Ottawa, and Saab offered to build the jet in Canada, in an effort to secure support for its previous bid, which it lost to Lockheed Martin. Since then, Saab has also emerged as the preferred candidate to supply Canada with its future airborne early warning and control (AEW&C) via its GlobalEye.

In April of this year, McGuinty confirmed that Ottawa was still reviewing its earlier plan to buy 88 F-35s.

“The review of the purchase of the F-35s is continuing… We are taking the necessary time to study very, very closely the question of the fighter fleet,” McGuinty told the Senate’s defense committee.

The split-buy option emerged since Canada has already made a firm commitment to buy 16 F-35As to start replacing its aging CF-18 Hornets. Canada’s industry also has a significant degree of involvement in the Joint Strike Fighter program.

Canada currently has around 75 CF-18A/B+ jets and has also added 18 upgraded former Royal Australian Air Force (RAAF) F/A-18A/Bs, plus seven more as spares, to help bolster its fleet.

Of Canada’s first 16 F-35s, four have already been paid for in full, while parts for eight others have also been purchased. The first Canadian F-35s were expected to be delivered for training at Luke Air Force Base, Arizona, in 2026.

Back in 2023, Canada’s Liberal government announced plans to buy 88 F-35s, a decision that appeared to bring closure to what had already been a very protracted process. You can read about this here.

However, amid growing trade tensions and a war of words with the United States, Liberal Prime Minister Mark Carney launched a review of the F-35 program shortly after taking office in the spring of 2025.

There are other arguments for a split buy, too. Back in 2019, the cost of buying the planned 88 F-35s was put at $19 billion. Now it has rocketed to $27.7 billion, not including weapons and infrastructure.

Bill Blair, who was Canada’s defense minister when the review of the F-35 buy was launched last year, pointed to the advantages of a mixed fleet, saying it would give the RCAF more options to handle different types of threats.

“What happens if you have to persist in that space for months and months and years? The tool that you use, is it the right tool to do that job?” Blair said. “We need to have a whole wide range of capability sets to deal with all the eventualities that we could face.”

Were Canada to procure the Tempest, it would surely have to wait longer than 2035 — the prospect of GCAP’s fighter entering service at this date, as planned, is highly unlikely. Canada would be fourth in line behind the three core partners. Ottawa would need to buy more F-35s, perhaps around two thirds of its original intended number, or around 60 aircraft, and also keep the best of its CF-18s in service for longer, if that’s even possible. The Hornets are getting very old and disappearing from service abroad. Supporting them will become increasingly problematic. When the Tempest finally arrived, it would provide a flipped high-low fighter mix. This is essentially the same approach that the United Kingdom, Italy, and Japan — all current F-35 operators — are taking.

However, the Tempest does appear to be especially well-suited to Canada’s fighter requirement.

The design of the jet will stress extreme range and a large payload — roughly twice that of the F-35A. Senior GCAP officials have said the jet could potentially carry enough internal fuel to fly across the Atlantic without refueling.

While these attributes are optimized for a future conflict in the Indo-Pacific region, they are equally applicable to dealing with the ‘tyranny of distance’ and the increasing Russian threat posed around Canada’s enormous land mass, which extends far into the highly strategic Arctic region.

“Both China and Russia have fifth-generation fighter aircraft and fifth-generation missiles that are able to go at much greater speeds and with much more that are holding Western allies at risk at this moment in time,” the commander of the Royal Canadian Air Force (RCAF), Lt. Gen. Jamie Speiser-Blanchet, said in the past.

Plans to arm the Tempest with larger air-to-air missiles offering a longer range than those currently used by any of the three GCAP partner countries have also been revealed, as you can read about here.

If Canada decides it wants a sixth-generation combat aircraft to tackle current and emerging threats from China and Russia, the GCAP might be the only realistic choice. The rival pan-European Future Combat Air System (FCAS) has collapsed, and there is little chance of Canada getting its hand on the Boeing F-47.

But any kind of split buy “would duplicate a certain amount of infrastructure and training,” Speiser-Blanchet admitted.

In some cases, however, there could be cost-benefit arguments in having a mixed fighter fleet, as well as the important factor of not relying entirely upon one source of this type of combat equipment.

There is also the question of how feasible it would be for Canada to join GCAP at this point, at least in terms of industrial participation and steering requirements. The latter point seems next to impossible, with national requirements already set, and most of the workshare agreement has also been divided up between the three partners.

The same applies to India, which has also looked at joining GCAP in the past.

There has been talk of Saudi Arabia possibly joining GCAP in some capacity, and, more recently, Poland has been reported as being interested in buying the aircraft, too.

With that in mind, Canada’s best shot might be to buy the jet ‘off the shelf,’ rather than hope for industrial windfalls.

At the same time, Canada and the United Kingdom are partners on some other key military programs, including the Royal Canadian Navy’s future River class Canadian Surface Combatants, derived from BAE Systems’ Type 26 design for the U.K. Royal Navy.

Returning to the Tempest, the broader GCAP program still has to survive considerable challenges, both technical and political, that lie ahead.

As we have explained many times in the past, the process of creating an all-new fighter, especially one incorporating stealth technologies, brings very lengthy development times and high costs.

At this point, BAE Systems is in the process of building a demonstrator as part of the GCAP program, with a first flight planned by the end of 2027.

The latest rendering of that demonstrator appears at the top of the story. Notably, it retains the Typhoon’s EJ200 turbofan engines, with non-stealthy nozzles. The Tempest will have an all-new powerplant.

As we have argued in the past, the more time that passes, and the more deeply intertwined with the F-35 Canada becomes, the arguments in favor of a split fighter buy become harder to justify. Buying the Tempest would certainly not be the cheapest option, and would force a rethink of timelines, but it does underscore the fact that Canadian officials are casting their net wider, looking at very high-end capabilities, and seeking to build deeper strategic relationships outside of the United States.
