US Missile (1950/60s) Query!!!

Someone please remind me: what was the name of the 1950/60s US nuclear armed surface-to-surface missile whose lethal range is greater than the range of the missile itself? I understand that the crews who launched the missile had only a few seconds to take cover.

Just spent 20 minutes going through Wikipedia without much luck!

Best Wishes and Thank You

Shame … I was hoping it was the BOMARC,and then I could have posted a photo of Miss Bomarc…
If you scroll to the bottom of this page you can see the lovely Fran Frost…

Obviously, I was mistaken (if your interpretation is correct).

Just another assumption. Alertken’s post always contain a lot more gen than most wordier posts, but sometimes may be a bit ‘telegrematic’. 😉

The assumption seemed appropriate… considering he listed the “Radius of lethality” in KM ONLY!

I expected he would be trying to show a comparable set of numbers, rather than throw out numbers in two differing and incompatible measurement systems without any attempt to relate them.

Obviously, I was mistaken (if your interpretation is correct).

Ummm… this cannot be correct.

Why not? You assumed a mile/km alternative – Alertken, meant ranges of either 2.5 or 1.24 miles, depending on unit – as you’ve (re)found.

Honest John M31 was deployed in 1954 with a range of 12 miles.
The improved M50 version was deployed in 1960 and had a longer range.

Little John M51 was deployed in 1961, and had a range of 18.2 km (11.3 miles), with a variable-yield W-45 nuclear fission (1-10 kT) warhead.

a range of 2.5/1.24miles

Ummm… this cannot be correct.

It is either 2.5km/1.56mi, or 2.0km/1.25mi.*

8 kilometers = 5 miles (approximately).

1 meter = 3.28 feet. 1 km = 3,280 feet. 1 mile = 5,280 feet. 1 km = .62 miles.

EDIT: *the latter…

The Davy Crockett could be launched from either of two launchers: the 4-inch (102 mm) M28, with a range of about 1.25 mi (2 km), or the 6-in (155 mm) M29, with a range of 2.5 mi (4 km).
The M-388 round used a version of the W54 warhead, a very small sub-kiloton fission device. The Mk-54 weighed about 51 lb (23 kg), with a selectable yield of 10 or 20 tons (very close to the minimum practical size and yield for a fission warhead) up to 0.5 kiloton.

Painted Red?

I recall seeing a color photograph of a Davy Crockett training round that was painted bright red.

Why am I thinking of a large winged, flying missile, which had a very short range? Painted Red? Maybe only a development weapon and not deployed?

Davy Crockett truck/jeep mounted recoilless gun system.

155mm M-29 or 120mm M-28 artillery pieces fired XM388, a spigot with Mk.54 warhead of 10-20tons yield, over a range of 2.5/1.24miles (J.N.Gibson, History of US Nuclear Arsenal, Bison,1989). Radius of lethality 2.5km. In Service 1962-67. Stated reason for phase-out was realisation that a Sergeant could take the escalation decision.

perhaps the Davy Crockett?

Perhaps you are referring to the Mk. 54 Davy Crockett, a recoiless rifle nuclear round? Do not think it was necessarily lethal to the launching crew, but is was the shortest range surface to surface round if I recall, and indeed would have been interesting to say the least. Not a missle per say, so may not be what you are looking for.
