Few people realize how hard it is to bring a new submarine launched rocket into service. France is to be congratulated.

Herald1234    Impressive achievement on video, shows a very rapid and clean flight profile.   12/2/2006 10:05:18 PM
Was that an aerospike on its nose?

Yes Herald.Like the Trident 2 and for the same reason.
In fact M51 is very close to Trident 2 by its performance, concept, weight and size.
Compare to former M5 which should have been already deployed with initial program, M51 is cheaper because extended nozzle which add a lot in price to get a marginal gain in performance (few hundred meters /seconde ant the end) were cancelled.Also some more conservative design for some parts and reduction of number of warheads.Plus elimination of actual testing of impact of depth charges agaisnt the sub on reliability of missile replaced by numerical simulation.
As it need less test we save more than 2 billion € in the program by reduction of prototypes.
However M51 is an improvement vs Trident 2 on antimissiles and laser weapons: fast burning stages, antilaser devices, stealthiness of bus and warheads, and of course like M4/M45 more decoys and more sophisticated decoys  than their US counterparts as we can not afford 3 warheads per target and saturate antimissiles systems.
Range of french missiles are volontarly underestimated (*) to protect our limited force.But a simple calculus show that the missiles should have a range between 9000 and 14 000 km depending the load of decoys and warheads and of course if it fired toward east or west.
This for public information.
(*)  : M45 supposed to be at a time 5000 km range has been fired toward Guyana at more than 6500 km and toward east (so retrograde and losing the additional rotation speed of earth which impact a lot ) end of the nineties.
 
BTW herald, do you live on east coast? I live in Paris but I'm sometime on east coast.

I think that they fired aerospike deployed the first test to avoid a source of failure and get maximum data the first test.

I should mean deployable nozzles instead of extended.It seems that deployable nozzle was cancelled at least for the second stage.

I bounce around a lot as I travel as a contractor, FS. I live in Atlanta in the US state of Georgia at present, but I am a Hoosier (a native of the American state of Indiana) and that is what I actually call home.

I know that at one time there was serious consideration to use the M5 as a replacement  for the French  IRBM  force  on the Plateau de Albion (ironic name that is), but that went the way of the S3D IRBM retirement.

Just out of curiousity, did France, ever consider building a TEL for the M51 as a landbased mobile missile? As I review it, it is astonishingly close to a D-5 in operational parameters. The D-5, in its own right, could be a formidable ICBM, if we were to landbase it in the US.

I see no reason, why if France or the US felt the need, either nation could not  doo such a thing.
