Description
The Flare Mk IV has a tubular body containing the candle unit, and the parachute, which is made of cotton. The tail end of the body is closed by a closing dome, and has four tail fins.
The body is closed at the nose end by a diaphragm having a bush into which is screwed a nose plug or the fuze. The flare composition is contained in a candle case together with some priming composition and a primed cambric disc at the nose end. a quantity of clay held between millboard discs, and a felt washer at the tail end. A lid is riveted to the tail end of the candle case. A shackle attached to the lid connects the candle unit with the suspension rope of the parachute.
A suspension band having two removable suspension lugs, one for attaching the flare to a Universal bomb carrier, and the other for attaching it to a Light Series bomb carrier, is secured to the flare body. Seven flares may be carried in Cluster, No. 1 Mk I, and four in S.B.C. 250-lb.
The 4.5 inch Reconnaissance Flare Mk I is similar to the Flare Mk IV, but has larger tail fins, a Silk Parachute Mk II, a brass disc over the flash hole in the diaphragm, and a candie case which is not strengthened in the region through which the lid rivets pass. The Reconnaissance Flare Mk II is similar to the Flare Mk IV, but has larger tail fins, a Silk Parachute Mk IV, a brass disc over the flash hole in the diaphragm, and a candle case which is not strengthened in the region through which the lid rivets pass. The Reconnaissance Flare Mk III is similar to the Flare Mk IV, but it has larger tail fins and a brass disc over the flash hole in the diaphragm, and its candle case is not strengthened in the region through which the lid rivets pass.

This flare is manufactured to give two types of steady colors, red or green, or four combinations of colors and stars; green with red stars, red with green stars, red with yellow stars, or green with yellow stars.
