French nuclear missile ASMPA-R
An important component of the nuclear arsenal of the French armed forces is aviation The ASMP missile entered service about 40 years ago and has since undergone several major upgrades. The latest upgrade is currently being completed, and the finished product is being delivered to the military. The Air Force previously received the improved ASMPA-R missile, and now it will also be available for use by naval aircraft.
Ways of development
The first version of the ASMP (Air-Sol Moyenne Portée—air-to-ground, medium-range) missile was developed by Aérospatiale and entered service in 1986. In the 2000s, the first major modernization project, the ASMP-A (Amélioré—improved), was developed. These missiles entered service in 2009-2010 and remain in service to this day.
In France's current strategy, ASMP missiles play a specific "pre-strategic" role weaponsThey are intended to be used as a final warning before a full-scale strategic strike. For this reason, the ASMP(-A) was not mass-produced. Only 90 of the first version and 54 upgraded missiles were manufactured.
Since 2014, the French armed forces have been considering a new modernization project. The need for such a project was justified by the expected obsolescence of the existing missile, as well as the changing military and political situation in Europe. The decision to develop a new project was made in 2016.

The advanced modification of the missile was designated ASMPA-R (Rénové, meaning "updated"). The lead developer of this project was the French branch of the international company MBDA, which acquired the assets of Aérospatiale in 2001. According to initial plans, the design was to be completed in the early 1920s, and the completed missile would enter service by the middle of the decade.
The ASMPA-R project was built on an existing one, which gave grounds for optimism. During the development phase, it encountered unforeseen challenges and restrictions, such as the 2020 quarantine, but this did not prevent the project from being completed on schedule.
In testing and in service
According to available reports, flight tests of the ASMPA-R missile began at the very end of 2021. A production Dassault Rafale fighter-bomber carried the prototype. It delivered the missile to the designated test site, completed the necessary preparations, and released it. The tests were reported to be successful, but no further details were provided. Testing continued early next year.
Testing and design refinement continued until 2022-2023. The ASMPA-R confirmed all design characteristics and was recommended for adoption. By 23, these missiles had already been delivered to units under the Strategic Air Command. Rafale fighters with the appropriate hardware and software became their standard launch vehicles.
In May 2024, the new missile was used for the first time during the Operation Durandal strategic forces exercise. It was reported to have successfully destroyed a potential enemy target and confirmed its capabilities. Following the exercise, photographs of the carrier aircraft and the missile in flight and during launch were published. However, the military department deemed it necessary to airbrush out the munition.
The Defense Ministry's plans also included the adoption of the ASMPA-R missile by naval aviation. The necessary preparations have been underway for the past few years, and they recently yielded the desired results.
On November 13, 2025, a Rafale-M carrier-based fighter jet launched a new missile as part of the Operation Diomede exercise. It was reported that just a few days before this event, the ASMPA-R missile had been officially accepted into service with naval aviation.
Thus, the ASMPA-R project ultimately achieved the desired results. The new "pre-strategic" missile has entered service with the Air Force and Navy. It will be used to update their arsenals and maintain essential combat capabilities. At the same time, air units will not have to radically redesign their weapons systems to accommodate the new missile.
The ASMPA-R missiles are expected to remain in service until at least the mid-1930s. After that, the Air Force and Navy will be expected to receive a new munition of the same class. The advanced missile, designated ASN4G, is currently in the early stages of development. It is scheduled to enter service by 2035, after which time there will be some time to upgrade the arsenals and retire older ASMPA-R missiles.

Technical features
The ASMPA-R is a long-range, supersonic missile armed with a nuclear warhead. It is designed to engage a variety of ground and sea targets. This missile should be classified as a tactical nuclear weapon, but France views it for a different purpose.
The rocket has an elongated, complexly shaped body. Its main body is cylindrical with an ogive fairing and a conical tail. Large protruding units equipped with air intakes are located on the sides. The tail contains X-shaped surfaces. The rocket achieves flight using lift generated by the bottom of the body and the side units.
The vehicle is 5,4 meters long with a cylindrical diameter of 350 mm. Its wingspan is 960 mm. Its launch weight reaches 840 kg. The payload weight is not disclosed.
The ASMPA-R is powered by a liquid-fueled ramjet engine. This powerplant limits the minimum launch speed of the carrier aircraft, but allows acceleration up to Mach 3. Several flight profiles with varying altitudes and maneuvers are possible. According to publicly available data, the range can reach 600 km.
The missile is designed to strike targets with known coordinates. Flight control is provided by an autopilot with inertial and satellite navigation. No additional target acquisition or homing capabilities are provided.
All ASMP missile variants, including the latest ASMPA-R, carry only thermonuclear warheads. According to various sources, the latest missile retains the TNA warhead from the previous variant or has a new one. The warhead used has a variable yield, ranging from 100 to 300 kt.
Unlike previous versions, the current ASMPA-R missile is intended to be used only by Rafale aircraft in their land-based and carrier-based configurations. These fighters will remain in service for the foreseeable future, and adaptation of the missile to new launch vehicles is unlikely to be necessary.
Disabled
France is a member of the "nuclear club," but it can't boast a large arsenal. Its nuclear forces comprise only two of the three necessary components—sea and air. Quantitative indicators also leave much to be desired. According to available data, no more than 50 missiles are deployed on submarines, and the same number of munitions are carried by combat aircraft.
Overall, the airborne component of nuclear forces is small and limited in capabilities. However, the armed forces have no intention of abandoning them and continue to develop them to the best of their ability. Recently, they completed the modernization of an existing missile and accepted it into service with two combat aviation branches. Furthermore, development of a next-generation munition is underway.
