    France Completes World's First Vertical Strike Of Laser-Guided AASM
    By PIERRE TRAN
    Published: 9 Jul 2010 08:52


    PARIS - France claimed a world-first vertical strike of a laser-guided AASM smart munition on July 9.

    "The Direction Générale pour l'Armement (DGA) completed successfully Thursday June 17 2010 the first firing of an modular air to ground weapon (armament air sol modulaire - AASM) in a laser version at its Biscarosse site," the procurement office said in a statement. "This firing of a laser guided munition with a vertical impact constitutes a world first," the DGA said.

    The firing was part of a feasibility study awarded to Safran group's Sagem in 2008.

    A Rafale strike fighter flying from the DGA test flight center fired the laser guided AASM out at sea at a height of 13,000 ft and 25 km from the target at the Biscarosse missile test center. The target, made up of concrete blocks, was designated by a ground laser placed a few hundred meters away. A GPS reading had been entered which deliberately gave coordinates several tens of meters away from the target, to see whether the laser guidance would correct the targeting.

    A vertical strike is intended to reduce damage and deaths in urban use, the DGA said. This version is also intended to be use against moving targets at sea or on ground.

    A laser version of the AASM follows the initial GPS/inertial-guided AASM propelled bomb, and an infrared model is currently undergoing operational and technical tests.

    Tests of the laser AASM will continue in the year.

    A valid M51 missile weapon system for the submarine The Terrible

    AFP | 10.07.10 | 12:21
    A shot of the new M51 nuclear missile carried Saturday from the Terrible allowed the validation of this weapon system nuclear submarine ballistic missile ( SSBN ) which will be commissioned in 2010, announcement in a statement the Department of Defense . Herve Morin , Minister of Defence, expressed his great satisfaction after the success of the launch of a strategic missile SSBN M51 performed as still no nuclear warhead , " the statement said. " This test validates the ability to make a terrible shooting conditions operational , it was done in strict compliance with commitments France's international , "the Ministry of Defence. The missile was fired Saturday at 9:32 from the Bay Audierne ( Brittany ), south of the tip Penmarc'h . The fallout area is at central North Atlantic , hundreds of miles from any coast . The flight of the M51 was followed by techniques Branch Armaments Biscarosse and Quimper , and by Monge , building and testing measures responsible for monitoring the test off . air and maritime areas had been temporarily reserved for this test. The Terrible had made his first shot of M51 on January 27 after three firings from land-based facilities in 2006 , 2007 and 2008 . The missile - sea- land - strategic ballistic missile submarines is designed for new generation, starting with the Terrible, launched in March 2008, and who will 16 copies .

    France has a few (~100) "tactical" warheads carried by ASMP-A supersonic cruise missiles. These very interesting weapons (with a max yield of 300 kT) could be used, according to French doctrine, to fire warning shots to an advancing enemy army.


    Both the ASMP-A and the Kh-31 are supersonic, ramjet-powered, missiles that can be launched by tactical aircraft. The difference is that the ASMP-A is heavier and only available with a nuclear warhead.

    Le Triomphant SSBN / M51 Weapons System Validated In Operational Conditions

    Defence Minister Jean-Yves Le Drian expressed his satisfaction today after the successful launch of an M51 strategic ballistic missile by the nuclear-powered missile submarine (SSBN) Le Triomphant this morning at 9:18 a.m. from the Bay of Audierne, in Finistère county.

    He extends his warmest congratulations to all the women and men of the Ministry of Defence, the Commission for Atomic Energy and Alternative Energies (CEA) and the companies who contributed to its success.

    The missile was monitored throughout its flight phase from the test center of the Directorate General of Armaments (DGA), including the test and telemetry ship “Monge”.

    The impact zone is located in the North Atlantic, several hundred kilometers from the nearest coast. As always, this test was conducted without a nuclear warhead and in strict compliance with France’s international commitments.

    This firing validates the operational capacity of the overall Le Triomphant weapon system, and again demonstrates the excellence in high technology that French industries are implementing in this area.

    The M51 missile today is fitted to three of the four next-generation missile-launching nuclear-powered submarines (SSBN-NG).

    The conversion of the entire Force Stratégique Océanique to this new missile is expected by the end of the decade.

    New details about the French nuclear forces

    As the Le Mamouth blog writes in the Dissuasion: from the administration of the French president in connection with the visit of the head of state to the nuclear-powered submarine with ballistic missiles S 619 Le Terrible (type Triomphant) has already become a tradition to include in the press distribution materials include some interesting figures. Thus, it became known that the visit was provided by 260 marines (almost 10% of the total number of the Marines and Force Maritime Forces fusiliers marins et commandos (FORFUSCO)) and 120 gendarmerie servicemen.

    It was reported that the air component of the French nuclear deterrent forces includes "50" fighters Dassault Rafale and Mirage 2000NK3, and this figure is usually not disclosed, but now it has become known to the uninitiated in this closed kitchen. Knowledge of the number of Mirage 2000NK3 fighters in operation (the total number of aircraft of this modification at the end of December 2016 was 29 units - bmpd) makes it possible to calculate the number of Rafale fighters from 1/4 Gascogne squadron involved in nuclear deterrence tasks. However, it should be recalled that these aircraft are also involved in the implementation of air defense and the conduct of operations against IG in the Middle East and against Al Qaeda in Africa. This is the most multifunctional and least expensive component of the French nuclear forces.

    It also became known that in the French Navy, the SSBN made almost 500 combat services in 1972 (now one of the boats is on the 492nd combat service). Also, the fact that from the autumn on the French SSBNB will be served by women has been confirmed.

    Effect of nuclear weapons - implosion?

    Post  Aristide on Sun Apr 29, 2018 9:56 am

    I have a question regarding our nuclear weapons.

    I dont know if russia also did under water tests as we did but i did read something about our tests in the south pacific and there is one aspect, that i dont
    understand. When the nuclear bomb explodes, it creates an enormous "suction" effect.

    Things are pulled towards it. Air pressure drops enormous. The water level drops down around the nuke and from above it looks like someone pulled the pluck.

    After a second the effect reverse and the shockwave expands outwards.

    Does anyone know what causes this effect? I believed the entire process is expansive from the beginning.

    I think it suck the air around it because of the fire it creates.

    I've seen somewhere nuk explosion are the fastest to kill then it's the thermobaric bombs. I think it was in the tv show walking dead when they destroy the medical center.

    It doesnt create a fire. It detonated under water. The process is incredible complex. One micrsecond after detonation there is a ball around the center, whioch is hotter than the core of the sun and has a
    diameter of 150m. The matter around it (air or water) gets ionized and doesnt allow light to travel through it.

    Thats why you see two flares. One when teh bomb detonates and a second later, when the plasma ball has cooled down to 35.000 °C light again can travel.

    So what you have is like 1 million °C in first second and it cools down to 35.000 °C within just 3-4 seconds, because the Plasma ball expands.

    That "vacuum" effect only exists during this first seconds. And its incredible powerful.

    We made a huge mistakewhen we did Opération Canopus in 1968.

    The bomb was our first hydrogen bomb and used Plutonium as initial bomb.

    The bomb was much more powerful than our scientists expected. It was a big show for France and we did send almost half of our fleet there. When the bomb went off, the explosion was far too powerful. The vacuum effect was so strong that our aircraft carriers and destroyers broke almost all windows. The ships started to get pulled towards.

    The staff started to punch their own chest because they could not breath anymore. It was like the air was sucked out of their lungs. After few seconds the effect reversed and the shockwave came.

    Thanks god nobody died but we had some real damage on our vessels. And some damage was done to Samoa.

    Not a physics major but the first thing that comes to mind would be that what you are assuming is a 2 part action is actually a 3 part act.
    - initial displacement due the explosion creating a vacuum
    - immediately followed by the air and or water returning to occupy the vacuum
    - then the blast waves generating outwards

    Thats possible. Its interesting and when i read it i learned many effects i wasnt aware of.

    What you say makes sense. I guess many aspects that happen in the inner core are still unknown or not well understood

    Its called cavitation. With relation to nuclear subsurface explosions, try reading this: http://www.iaea.org/inis/collection/NCLCollectionStore/_Public/11/514/11514122.pdf?r=1

    Although you describe the nuke detonation starting with an apparent implosion, that is in fact the second phase. At detonation the first pressure wave in advance of the plasma bubble expands outwards, but at the surface the displacement is a barely noticeable few metre up swell, before the subsurface bubble collapses... dramatically. The pressure wave then rebounds and expands and collapses several times more in a diminishing oscillation.

    An example of such cavitations can be seen here... https://youtu.be/cp5gdUHFGIQ?t=271

    Thank you very much. Thi helps alot. Did russia also perform underwater tests as we did?

    I really wonder why the Canopus test ended in such a chaos. I mean France had tested many nuclear bombs before. We almost accidently destroyed 40% or our own fleet.

    My guess is the effects rise extremly with the size of the bomb?
