Royal Navy’s Stratus Missile Programme Moves Toward Full-Scale Tests in 2028

Core Event: First Full-Scale Tests Planned for 2028
The Ministry of Defence confirmed that the first complete system trials of the Stratus long-range missile family will commence in 2028. Defence Minister Luke Pollard said development has already progressed through airframe, engine, warhead and seeker testing, with modelling and subsystem trials to continue up to the 2028 milestone.
Background & Context: Evolution and Variants
The Stratus programme, originally the Future Cruise/Anti-Ship Weapon (FC/ASW) and later the Future Offensive Surface Weapon (FOSW), now comprises two weapons:
- Stratus LO (Low Observable) – a stealthy, subsonic cruise missile with a passive multimode seeker and Automatic Target Recognition for deep-strike land and surface targets.
- Stratus RS (Rapid Strike) – a high-supersonic, highly manoeuvrable missile with an active seeker for anti-ship and SEAD missions.
Both variants are being developed jointly with France and Italy. France has committed to the RS version for the Rafale jet’s future SEAD/DEAD capability. The extent of component commonality between LO and RS has not been disclosed.
Data & Statistics
- Funding: The Defence Investment Plan allocates £1.4 billion to equip Typhoon aircraft and new frigates with Stratus.
- Platform Integration: All 13 Type 26 and Type 31 frigates under construction will be capable of carrying the missile in their Mk 41 VLS. Each Type 26 frigate houses 24 Mk 41 cells.
- Performance Targets: Minimum range 500 km, warhead weight >= 225 kg, and a target unit price of roughly £400,000 (excluding the warhead).
- Timeline Shifts: In 2021 the plan projected entry into service on Type 26 frigates by 2028. The MoD now expects both air-launched LO and surface-launched RS to enter service in the early 2030s.
Official Statements & Responses
Defence Minister Luke Pollard explained that the programme has moved beyond concept studies to hardware testing, covering the missile’s airframe, propulsion, warhead and seeker. The Ministry announced a formal review of the Stratus long-range strike programme, scheduled to conclude by 1 September. The review will assess progress, cost, and alignment with the Royal Navy’s distributed-maritime-air-defence architecture.
Conflicting Reports & Gaps
- The final national procurement mix for the Stratus family remains undefined, with no public breakdown of LO versus RS quantities for each partner nation.
- MBDA has not disclosed the degree of parts commonality between the two variants, leaving uncertainty about logistical implications.
- While linked to the Future Air Dominance System (FADS) and potential uncrewed launch platforms, the Type 9X uncrewed vessel programme is still only a concept.
Timeline of Key Milestones
| Year / Date | Milestone |
|---|---|
| 2021 | Optimistic plan set for Stratus to enter service on Type 26 frigates by 2028. |
| 2028 | Commencement of first full-scale system tests for both LO and RS variants. |
| Early 2030s | Anticipated in-service entry for air-launched LO and surface-launched RS weapons. |
| 1 September | Completion of the MoD-mandated review of the Stratus programme. |
Why It Matters: Strategic Impact
Stratus is intended to restore a heavyweight, surface-launched land-attack capability to the Royal Navy after the abandonment of ship-borne Tomahawk missiles. By providing both low-observable and high-speed strike options, the missile family aims to challenge enemy air-defence systems and extend the offensive reach of the RN’s new frigates.
What’s Next
The September 1 review will determine whether the programme proceeds on schedule, requires acceleration, or faces adjustments. Decisions will shape the timing of full-scale testing, production planning, and deployment on Type 26/31 frigates and potentially on future uncrewed launch platforms.
