The mechanisms for ?ring the charge of a
torpedo and other devices usually found in the
torpedo represent no portion of my invention,
and are, therefore, not shown. It should be noted,
however, that torpedoes usually have inertia con
trol ?ring mechanisms or ?ring mechanisms con
trolled in some other fashion, which cause ex
plosion of the charge when the torpedo hits the
target. Usually, these mechanisms have an in
ertia switch or some other device in the nose of
the torpedo, and when a torpedo strikes a rela

At the depressed, preformed, or bent region
8, I dispose a plurality of openings circumfer
entially of the eye 5, and I ?ll these openings with
rivets 7 soldered into place so as to make the
chamber leak-proof. In operation, as shown in
Fig. 3, the towing-eye or very point of the nose
of the torpedo strikes the target T, and since this
auxiliary nose, or false nose, immediately begins
to buckle and collapse, the torpedo is slowed down
enough to allow time for the detonators to oper
ate to effect the detonation of the main charge
before the main torpedo body strikes. This slow
ing down is suf?cient to take the initial impact,
to prevent shattering of the torpedo body. The
tively rigid target, the nose and sometimes the
entire front of the torpedo may collapse, and thus 45 impact, however, is of sufficient magnitude to set
the inertia devices in operation to cause detona

I provide the body of the torpedo I with a sub
stantially conventional hemispherical nose 2, hav
ing the offset region shown at 3; and at this
offset region, I dispose the auxiliary nose 4 which
largely in this manner: when the target is struck,
the false nose or auxiliary nose will begin to
buckle at the region 6, the region occupied by the
rivets l’, and the pressure of the liquid inside of
the chamber will expel the loosened rivets, and

The speci?c dimensions selected for the aux

vention, but the design will, of course, be so se
lected to have a de?nite relation to the speed of
operation of the torpedo, the important feature
being that point In, as it moves back toward the
of the body, a hemi-ellipsoidal false nose having
a circumferential ?ange at the base with an out
