French Deep Strike: A Review of Ongoing Development Projects

Picture: MBDA

As European states advance their rearmament efforts in the long-range strike domain, France stands out for the sheer number of ongoing national-level development programs, setting it apart from other European states that — for better or worse — have chosen to rely on American technology to fill urgent capability gaps.

This post reviews France’s ongoing long-range and deep strike programs across four capability areas: rocket artillery, cruise missiles, ballistic missiles, and affordable one-way effectors.

Perhaps unsurprisingly, the breadth of these efforts raises questions about financial and industrial feasibility. That said, France’s recent, somewhat decisive embrace of affordable long-range strike solutions could position it as a European leader in this capability area.

French long-range and deep-strike programs

In total, French manufacturers are developing 13 distinct long-range and deep-strike systems, summarized in the table below and explored in greater detail in the following section.

Rocket artillery

As part of the FLP-T program, French manufacturers are currently developing two competing designs for a 150-kilometer guided artillery rocket, conceptually similar to the American GMLRS-ER fired from HIMARS.

MBDA and Safran are offering the Thundart, while ArianeGroup and Thales are jointly offering the FLP-T 150 (likely a placeholder name). The program seeks to procure at least 13 French MLRS systems by 2030, implying that the winning design will reach initial operational capability in the early 2030s.

While there appears to be an appetite for a French rocket artillery missile in the 150–300 kilometer range, comparable to the American M57 ATACMS or the South Korean CTM-290, no such system is currently planned under the program. The FLP-T, however, envisions a 500-kilometer-plus long-range strike capability, discussed in the next section.

Land-attack cruise missiles

France currently has three ongoing land-attack cruise missile programs.

The first is SCALP-EG Mk. 2, which, as the name suggests, is an evolution of the existing SCALP-EG air-launched cruise missile, likely incorporating improved guidance, target acquisition, and mission planning functions while broadly retaining the original airframe and preserving interoperability with the current fleet. The Mk. 2 is primarily intended as a life-extension measure, bridging the gap until France’s next-generation air-launched cruise missile enters service in the early 2030s.

That next-generation system is the STRATUS LO, developed under what was previously known as the Future Cruise/Anti-Ship Weapon program run jointly with the UK and Italy. STRATUS LO is one of two variants being advanced under the program, the other being STRATUS RS. STRATUS LO is a subsonic, low-observable land-attack cruise missile; STRATUS RS is a supersonic land-attack cruise missile with a targeted top speed of Mach 3 to Mach 5.

For France, STRATUS LO will primarily replace the SCALP-EG. While STRATUS RS will serve a general multirole function, it is also intended to provide more specialized SEAD/DEAD and time-sensitive targeting capabilities for the Rafale F5 fleet. STRATUS LO targets an initial operational capability of around 2032; STRATUS RS will likely not become operational before 2035.

Finally, MBDA is developing the Land Cruise Missile, a ground-launched land-attack cruise missile adapted from the Missile de Croisière Navale — France’s ship- and submarine-launched land-attack cruise missile, which reached initial operational capability in 2017. First test firings are planned for 2027–2028. The Land Cruise Missile is envisioned to fill the 500-kilometer-plus range envelope within the FLP-T program, with a likely range exceeding 1,000 kilometers and a potential initial operational capability in the early 2030s.

Ballistic missiles

The Missile Balistique Terrestre (MBT) program, led by ArianeGroup, represents France’s return to conventional ballistic missile capability after a thirty-year gap.

Two variants were unveiled as mock-ups at the Paris Air Show in June 2025. The first is a single-stage solid-propellant ballistic missile with a baseline range exceeding 1,000 kilometers, truck-launched from a standard transporter-erector-launcher. The second is a two-stage variant extending the range to 2,000 kilometers or beyond. Both draw heavily on ArianeGroup’s expertise in solid-rocket motors developed for the M51 submarine-launched ballistic missile and the Ariane launcher family.

The program was formally funded in the 2026 budget at an initial €15.6 million for feasibility work, scaling to roughly €900 million in total through 2030. A realistic initial operational capability for the single-stage variant is the early to mid-2030s; the two-stage variant is likely further out.

The two-stage variant may eventually incorporate a hypersonic glide vehicle, building on the V-MAX demonstrator program, successfully tested in June 2023 using an American-supplied sounding rocket. V-MAX2, the follow-on hypersonic glide vehicle demonstrator, is closer in design to the eventual operational system and was originally scheduled for testing in 2025, but was delayed after France decided to move away from reliance on American booster technology.

France is now awaiting the completion of the SyLEx two-stage sounding rocket, also supplied by ArianeGroup, which is needed to bring the projectile to altitude before resuming hypersonic glide vehicle testing. The sounding rocket is not scheduled to fly before 2027, pushing hypersonic-related testing likely into the late 2020s and eventual deployment well into the 2030s.

Low-cost long-range strike systems

Lastly, France is working on three separate long-range and deep-strike programs focused on creating affordable mass.

The first is the MBDA One-Way Effector (OWE), a jet-powered long-range strike drone with a range of 500 kilometers and a 40-kilogram warhead. The French armaments agency (DGA) placed a confirmed development and production order in January 2026, with initial deliveries to the French armed forces planned for mid-2027. MBDA claims a production surge capacity of up to 1,000 units per month through partnerships with automotive industry manufacturers. The initial contracted quantity has not been disclosed, but it likely amounts to several hundred.

The second is MBDA’s Crossbow, a heavier one-way effector carrying a 300-kilogram warhead over a range of 800 kilometers, sharing similarities with the mini cruise missile designs popularized by Ukraine, and pursued by several other manufacturers. No production contract has been confirmed.

The third is Chorus, developed by Turgis & Gaillard in partnership with carmaker Renault, which envisions a deep strike system carrying a 500-kilogram warhead over 3,000 kilometers at approximately 400 kilometers per hour. The system has commonly been described as a drone, though it appears to share more similarities with a low-cost heavy cruise missile design, similar to the Ukrainian FP-5 Flamingo. The DGA has awarded a €35 million validation contract, with around ten drones to be delivered for evaluation by summer 2026. If trials succeed, a ten-year framework contract worth approximately €1 billion could follow.

France is also a signatory to the European Long-Range Strike Approach (ELSA) OWE 500+ Letter of Intent, signed in February 2026 by six European nations, which envisions a jointly developed one-way effector with a range exceeding 500 kilometers and a unit cost below €100,000. The program is in its feasibility phase and has not yet produced a development contract. MBDA’s OWE could serve as an industrial baseline for a multilateral European long-range strike effort, though it remains to be seen whether the ELSA program converges on this design or another.

Outlook and challenges

France’s long-range and deep-strike portfolio is, on paper, the most ambitious in Europe. Across all capability tiers, the French industry is developing or has recently contracted more distinct long-range strike systems than any other European state.

The binding constraints will be financial capacity and industrial bandwidth. MBDA and ArianeGroup are simultaneously running development programs across nearly every conventional long-range strike category reviewed above, while sustaining existing systems and executing nuclear modernization commitments — ASMPA-R, ASN4G, and M51.4 — that absorb significant engineering capacity.

Timeline risk is also apparent. Several programs are already running late, and sequential dependencies mean that a slip in any one program could propagate through the others. The FLP-T capability gap — the window between the retirement of the current MLRS force and the delivery of FLP-T systems — is a confirmed near-term issue with no fully resolved solution. More broadly, as with the rest of Europe, more comprehensive French rearmament in the missile domain cannot be expected before the mid-2030s, leaving the late-2020s window, which European officials have identified as potentially the period of greatest danger, unaddressed.

That said, French efforts have, in part, been more decisive than those of other European states. This is especially true of more affordable deep-strike capabilities, where France has placed firm development and procurement contracts — if only in limited quantities and for proof-of-concept purposes — while other European states remain stuck in planning phases. If France stays on course and pursues these programs with discipline, it could emerge as Europe’s leader in this capability area.
