Ukraine's adoption of the Swedish Gripen fighter

Ukraine’s calculus for air power is changing. If substantial deliveries of Saab’s JAS 39 Gripen materialise—as suggested by Stockholm and Kyiv’s new letter of intent for 100–150 aircraft, with first examples discussed for the second half of this decade—the utility of the Ukrainian Air Force (UAF) could shift from a primarily defensive, attritional posture to something far more agile, survivable and economy-minded.

The operational value proposition

Gripen was conceived for a small state facing a larger adversary’s long-range missiles and massed aviation—an echo of Ukraine’s own problem. Its core strengths are threefold: true dispersed operations from road bases; robust electronic warfare and modern sensors; and low operating cost with quick turnarounds by small ground crews. In Swedish service concepts the C/D variant of the fighter can fly from 800×16-metre stretches of highway with minimal support, making it unusually tolerant of runway damage and missile raids. For the Ukrainian Armed Forces, that has had fixed bases repeatedly targeted, this basing model is strategic rather than cosmetic.

Survivability and lethality against Russian systems

Against the S-300/400 umbrella and Su-35/57 patrols, survivability is a blend of signatures, tactics and emissions control. The E-series adds an AESA radar (Leonardo ES-05 Raven), a passive IRST (Skyward-G), and the Arexis-family electronic warfare architecture; together they enable silent search, long-range cueing and sophisticated self-protection. Paired with long-range air-to-air missiles such as Meteor, this allows standoff engagements while minimising time in the threat envelope. These attributes are not theoretical marketing: they are embedded in the E-series design and already fielded with Sweden and Brazil.

Dispersed operations as an answer to Russia’s strike complex

Russia’s repeat use of ballistic and cruise missiles to crater Ukrainian runways argues for an air arm that can scatter, hide and regenerate. Gripen’s concept of operations—short take-offs, highway turnarounds, small maintenance footprint—directly reduces the payoff of those strikes. In practice that means more sorties generated after a raid and fewer predictable patterns for Russian reconnaissance to exploit. For a country whose airbases are mapped to the centimetre by enemy ISR, that is a decisive quality.

Networking and coalition interoperability

Ukraine’s increasingly networked kill-chain—F-16s, Patriots/NASAMS, IRIS-T SLM, and Western ISR—demands fighters that are fluent in NATO datalinks. Gripen natively supports Link-16, a secure, encrypted NATO-compatible data transmission network, and an advanced national datalink lineage that Sweden has refined for decades, giving Ukrainian pilots a fused picture of threats and targets and enabling cooperative tactics with F-16s and ground-based air defence. This is particularly important for time-sensitive targeting against cruise missiles and glide-bomb carriers.

Weapons and mission flexibility

On weapons, the type brings breadth. The Meteor missile provides air combat options with a range in excess of 200 kilometres; IRIS-T/AMRAAM cover short and medium ranges; for maritime strike, the RBS-15 offers land-attack and anti-ship capability beyond 300 km—useful for pushing the Black Sea Fleet further from Ukraine’s coast and pressuring logistic nodes in occupied territory. The aircraft’s sensor fusion and EW also lend themselves to the suppression and deception of Russian air defences, supporting advanced SEAD (suppression of enemy air defences) alongside drones and loitering munitions.

Sustainment and tempo

A decisive wartime question is not just what a fighter can do, but how many sorties it can sustainably generate. Gripen has been repeatedly assessed as comparatively inexpensive to operate among Western types, and it was designed for rapid re-arming and refuelling by small teams. For a UAF that must husband fuel, spares and trained technicians while keeping aircraft dispersed, those attributes translate directly into higher sustained sortie rates and more combat air patrol time per litre and per man-hour.

Complementing, not replacing, the F-16

F-16s remain the near-term backbone of Ukraine’s Western fighter fleet and are already arriving from several European donors. Gripen would not displace that effort; it would complement it. The UAF could concentrate F-16s on missions where their large ecosystem shines—precision strike with a wide catalogue of munitions and Wild Weasel tactics (advanced electronic warfare to bait and destroy air defence systems)—while exploiting Gripen’s dispersed operations and EW survivability for air policing, cruise-missile interception, and opportunistic counter-air on the edge of Russian SAM envelopes. Mixed packages also complicate Russian counter-tactics by forcing adversary pilots and controllers to manage two very different threat profiles.

Industrial and timing realities

Utility is bounded by delivery and sustainment timelines. Public statements now describe a long-term package of 100–150 aircraft, with officials citing a roughly three-year horizon for first Gripen-E deliveries and some Ukrainian statements mentioning 2026 as an ambition. Saab says it can surge production and is even examining overseas assembly options if a Ukraine deal is concluded, which would mitigate—but not erase—lead-time and capacity constraints. Realistically Gripen’s impact will scale over several years, with early utility concentrated in pilot training, tactics development and initial operational detachments while logistics and weapons stocks build.

Phased force-integration plan

To realise the aircraft’s potential efficiently, Ukraine will need a phased integration plan spanning four overlapping stages:

1. Pilot and technician conversion (2025–2026)

Sweden’s offer includes training cadres at F7 Såtenäs and potential forward detachments in Central Europe. A nucleus of roughly 20 Ukrainian pilots and 100 technicians would rotate through Swedish programmes, building expertise not only in flight but in the unique dispersed-maintenance doctrine. This cadre would seed national training schools once aircraft arrive.

2. Dispersed-basing infrastructure and highway preparation (2025–2027)

Ukraine must adapt portions of her national road network with arrestor gear, fuel trucks and mobile shelters, following the Swedish “Bas 90” concept. Early investments—estimated at a few tens of millions of dollars—yield asymmetric defensive benefit by transforming dozens of highway segments into viable runways immune to single-point failure.

3. Initial operational capability (IOC) with 12–18 aircraft (2026–2027)

The first squadron would focus on air policing, cruise-missile interception, and sensor fusion with Western air defence networks. Meteor and IRIS-T stocks would be integrated progressively, and early missions would gather combat data for doctrine refinement.

4. Full-spectrum employment and industrial sustainment (2027 onward)

With 60–80 aircraft delivered and dispersed-basing routine, the UAF could mount simultaneous counter-air patrols, maritime interdiction, and electronic attack missions. Saab’s mooted local assembly or maintenance partnership in Ukraine would allow the country to build spares resilience and eventually re-export maintenance services to other Gripen operators in Europe.

Constraints and risks

There are, however, non-trivial constraints. First, the E-series is new and in high demand from Sweden and Brazil, so near-term airframes may be limited unless C/Ds are released or leased as an interim step. Second, weapons such as Meteor and RBS-15 require export approvals and stockpiles; aligning those with Ukrainian needs will take diplomacy and cash. Third, introducing a second Western fighter type adds training and maintenance complexity, even if mitigated by Gripen’s low per-hour cost and lean ground-crew model. Finally, Russia will adapt; dispersed basing complicates targeting but increases the burden on Ukraine’s logistics and air-defence pickets that must protect numerous temporary strips.

Strategic payoff

If the reported scale of deliveries is realised, Gripen offers Ukraine a wartime fighter optimised for surviving under missile pressure, fighting with modern sensors and EW, and sustaining high tempo at tolerable cost. In the near term it would reinforce air policing, cruise-missile defence and selective counter-air capacity; in the medium term, as numbers and munitions grow, it would expand the Ukrainian Armed Force’s ability to challenge Russian fighters and push the Black Sea Fleet further from Ukraine’s littoral. Most importantly, its dispersed-operations model helps to “break the map” Russia uses to plan strikes, turning every highway into a potential runway and every strike on a concrete base into a wasted missile. As a complement to the incoming F-16 fleet—not a substitute—the Gripen could prove a notably high-leverage addition to Ukraine’s airpower portfolio.

Dates and context: the Sweden–Ukraine letter of intent for 100–150 Gripens was announced on 22–23 October 2025; Swedish and Ukrainian officials have spoken of first deliveries roughly within three years, with some Ukrainian statements pointing to 2026 as an aspiration. Saab states it can double output if needed. These timelines frame when battlefield effects could begin to accrue.
