SHELL 155 ILLUMINATING (ERFB)
DESCRIPTION :
The payload is an illuminating candle attached to a parachute. Because this cannot be successfully ejected directly from the shell due to the high spin and velocity which still occur at the moment of deployment, this payload is contained within a steel canister with its own delayed ejection charge. When the canister is ejected, the delay ignites and simultaneously a drogue parachute deploys and anti-rotation fins open on the canister, drastically reducing velocity and rotation of the canister before the flare and parachute are ejected from it.
APPLICATION :
Since it has a low rate of descent, the candle continues to give good ground illumination over a wide area during its total burning time. This could facilitate redeployment of own forces but is more likely to be used for surveillance of enemy movement which might otherwise go undetected in darkness.
