The German 200-mm (7.9 in) spigot mortar leichte Ladungswerfer 40 is
an engineer weapon, intended for use against minefields, wire, antitank obstacles,
and weapon emplacements. It is of normal spigot design, the propellant case being
attached to the top of the spigot before the bomb is loaded. Fixed ammunition is
not used. The 200-mm spigot mortar bomb was described in Tactical and Technical
Trends No. 16, page 32.
The following additional information as to the mortar itself with
accompanying sketch have recently been received from a British source.

The 46 pound HE bomb (200-mm Wurfranate 40), a smoke bomb (200-mm
Wurfgranate 40 Nb), and "harpoon projectiles" are fired. The harpoon rounds are
said to be used to project cords by means of which mines or a network of charges
can be drawn onto dead ground.
c. The Equipment
This consists of a base plate, bipod mounting and spigot with supporting
(1) The base plate is of the familiar German mortar design, the bottom
being formed with strengthening webs and spikes.
(2) The bipod mounting is similar in construction to that of the 80-mm
and 100-mm German mortars, the recoil arrangements however being of a more
(3) The spigot consists of a drawn steel tube reduced at its lower end and
screw-threaded externally to receive the supporting arm and base piece. It is
bored transversely at its lower end to receive contact pieces and insulation for
the electrical firing mechanism.
A T-shaped contact tube is carried from these contact pieces up the
inside of the spigot and is maintained centrally by an insulating spacing washer
at the front end.
The front end of the spigot is closed by a screw plug which is bored
centrally to house a contact plug and insulating bushes, and also houses the firing
needle and spring. The front face is prepared with an undercut groove to form a
bayonet joint when the cartridge is placed in position.
(4) The base piece screws on to the spigot and is formed with a ball at
the rear end to engage in the socket of the base plate.
(5) The supporting arm is tubular and elbow shaped. The rear end is
formed with a boss which is bored to receive the spigot, the front end is solid and
is screw-threaded to receive a collar for positioning in the cradle.
