ASN-4G air-sol nucléaire fourth-generation

ASN-4G refers to air-sol nucléaire fourth-generation. while some voices are calling for the Deletion of airborne component of deterrence to achieve economies (which remained to be seen ...), in 2014 Minister of Defense Jean-Yves Le Drian, vigorously defended the strategic air Forces. The ASN-4g "was launched last summer with the development stage of the ASMP-A missile renovated. This will provide the component (Airborne) an aerobic missile capable of penetrating all future defenses until 2035 ", he began by saying on this subject. "Finally, studies on the successor of ASMPA, called ASN4G, has already begun," confirmed Mr Le Drian.

It "provides the political authority a wide range of strategic and military options, with a range of modes of action that gives real flexibility to the entire device. In particular, it contributes strongly on the decision of President of the Republic, exercise targeted strategic effects, or a final warning strikes', explained the minister.

"It also represents, he continued, an ability 'visible', which opens in case of necessity, space for a political and diplomatic maneuver (...) generates potential opponent for an additional constraint for its defenses thanks to the diversity of modes of penetration of our weapons, ballistic or aerobic, aircraft or submarines "and" by the redundancy that results, it puts our nuclear forces immune from an unexpected breakthrough in this or such area. " Finally, "the cost is moderate, given the issues of sovereignty," with "about 5% of the budget of deterrence in the next ten years," he added.

If France wants to maintain strategic air forces, it is important that upstream study programs be carried out in good conditions. The current ASMPA (Air soil medium range) Airborne has a range of about 500 km. It will be replaced by a system whose studies were launched in the summer of 2014. It is now called ASN4G and, according to the defense minister, "bold designs, using such technologies stealth or hyper-velocity at the forefront of developments in technology will be explored."

The Air-Sol Longue Portee (ASLP) was a longer-range version of the ASMP proposed as a co-development project with Britain. It would have had a range of 1,000-1,200 km and would replace the WE177 nuclear gravity bombs providing the Royal Air Force. The ONERA and MBDA are working on two projects successors of the AMSP/A.

The mid-life refurbishment of the ASMP-A which will enable the missile to maintain its operational capabilities during its second phase of life, facing air defenses. Discussions on the renewal of the airborne component were launched. It is at this stage of upstream studies to prepare for the renewal of the vector 2035, and that the longer-term carrier.

The ASMP program and airborne nuclear roadmap is one of the technical pillars supporting the chain of tactical missiles. Indeed, two large families of trades and key competences are specific to the field of tactical missile systems. On the one hand, in common with military Aeronautics are technologies that must be adapted for significantly more severe environments in light of performance suffering and of the specific constraints of design. Other hand, guidance missile terminal function must be accurate and provide penetration capability).

The strengthening of some specificities trades is necessary for:

  • propulsion with the necessary control technology Ramjet;
  • aerodynamics to cover a wide range of flight ranging from lower at the higher elevations.
  • mechanical and thermal environments resulting from its capacity of long-range supersonic flight;
  • the penetration of goals very defended due to its large ability to manoeuvre;
  • hardening of its electronic against attacks nuclear.
  • nuclear safety to ensure high reliability and security.

These technologies rely on a high level of skills in the areas of engineering, testing and expertise but also of the production. The nature of the program, these skills are strictly National. Thus, the financial effort dedicated to the development and maintenance of these sectors of excellence in the field of nuclear component Airborne ensures a return to 100% french in territory MBDA France and its subcontractors and partners, including many SMEs.

  • Missile with Ramjet PEA CAMOSIS from the March concept of ONERA - which would multiply by two the current performance The ASMP/A;
  • Super hypervelocity Ramjet PEA Prometheus missile with a flight testing of the LEA demonstrator initially planned for 2014-2015, which would multiply by a factor of four the current performance.

The main issues are the issues of penetration. This is to determine the right balance between speed, maneuverability and stealth. These questions are at the heart of the development of the successor to the ASMP-A. The two main technical solutions through two PEA: high supersonic and hypersonic. All activities developed through these two PEA will be directly or indirectly reused for deep strike and for new releases - probably supersonic - of the anti-ship strikes. The successors of the Scalp and Exocet now subsonic, supersonic are likely. Issues relating to future versions of the ASMP-A, Scalp and Exocet are very linked and form a coherent whole which aims to allow to have the technology at the right level and at the right cost. Thus, the day the decision to launch the developments preparing the successor to the ASMP-A will be taken, the manufacturer will have done its job bringing in the decision elements the technology level to maintain the capacity and credibility and the cost elements to make this decision as easy as possible.
