British Bomb, 1000 lb TI, No. B.16 Mk 1




The bomb consists of a cylindrical body with a dome-shaped nose cap welded on. The after body of the bomb consists of a sheet steel body cone. This after cone section is welded to a steel tail plate, which is press fitted into the after end of the central cylinder. A small notch is cut out at one point on the circumference of the tail plate. A projection from the end of the central body engages in this notch, properly positioning the tail plate and tail assembly. A steel tube, running axially through the bomb, is welded to a burster container at the nose end, and passes through a central hole in the tail plate at the tail end. The fuze adapter is threaded to this tube abaft the closure plate, holding the closure plate and tail assembly tightly in the bomb body.

Three banks of flares are placed in the central body cylinder. The ignition ends of the flares bear against one of two equispaced, primed cambric discs. A primed cambric tube is inserted in the central tube, and holes in the central tube provide a lead out to each of the primed cambric discs.

An ejection plate is located just before the first bank of flares and just abaft the hollow nose portion of the bomb. This ejection plate is welded to the central tube. In the nose is a short burster container with a flash hole in its after end, and additional flash holes located circumferentially around its upper portion. These latter holes lead into the empty cavity formed by the nose portion of the bomb and the ejection plate.

The Bomb No. B.29 is the only bomb of this series which does not contain candles. It is similar to the Bomb No. B.2, but has no primed cambric tube in the central tube, and no primed cambric, cardboard, or millboard washers in the bomb body. The bomb is filled with a quantity of powdered, colored pigment.

The Tail No. 57 Mk I consists of a tail cone to which a cylindrical strut is fastened by four fins. The arming assembly consists of arming vanes, an arming spindle, and an arming fork, which is positioned inside the cone by a spider. A locating slot in the forward edge of the cone engages a locating pin on the bomb. The cone is secured to the bomb by four bolts, housed in the cone ring which is riveted to the inside of the cone. The cone also has two celluloid inspection windows set into it.

The bombs are equipped with a single lug for British suspension, and two lugs, 180° removed, for suspension in American aircraft.

This series of bombs is a larger version of the 250 lb. T.I. Bombs, with the exception of the No. B.29, which has no parallel in the 250 lb. series. The individual bombs within the 1,000 lb. series, including the Bomb No. B.29, differ mainly in their contents. The Bomb No. B.29 is used as a daylight skymarker. It emits a cloud of colored pigment which is effectively visible for about four minutes. This bomb is called the “Skymarker Puff.”
