Default New U.S. ICBM coming

Hello All,

I just came across this article (see: http://www.spacedaily.com/reports/B...w_ICBM_999.html ), which says that a new ICBM is being developed to replace the Minuteman III. This will be interesting for both the sounding rocket and small satellite launch vehicle "worlds" (where the retired Minuteman missiles and/or their individual motors will become available for use), and also for scale model rocketry, as we'll have new scale subjects (the new ICBM, and the vehicles that will use the Minuteman rocket motors).

Yes, for decades it has seemed that the B-52 and the Minuteman would be permanent members of the U.S. nuclear arsenal (there's nothing wrong with a long service life as long as a weapon system remains relevant--particularly via upgrades--and dependable), and:

One innovation that would make the future U.S. ICBM smaller and more mobile (and thus also more concealable) is air-augmentation for its first stage. The Soviet Gnom ("Gnome," see: www.astronautix.com/g/gnom.html ) solid propellant ICBM--whose development ceased after the 1965 death of Boris Shavyrin, its designer, but whose air-augmented first stage design was proved by the scaled-down PR-90 missile (see: www.astronautix.com/p/pr-90.html )--weighed less than half as much as conventional designs with equivalent performance. Also:

Its much lower mass made mobile basing of the Gnom practical (not until the 1990s would Russia field a mobile ICBM, and it weighed 47 tons as opposed to the Gnom's 29 tons). Its air-augmented first stage motor, which was successfully tested just days after Shavyrin's death, had a specific impulse of 550 seconds, double that of a conventional rocket.
