Shorland S53 Air Defence

History

The S53 was the one Series 5 Shorland that existed because of what Short Brothers made besides vehicles. Shorts built both the launch platform and the missiles it carried — the Blowpipe, Javelin and later Starburst family of shoulder-launched close air-defence weapons — which gave the company an unusually free hand to integrate the two. The vehicle was first marketed as the Mobile Air Defence System, then the Mobile Air Defence Vehicle, and finally, since a vehicle-mounted system is mobile by definition, simply the Air Defence Vehicle. Its stated purpose was the defence of airfields and other key installations, and of supply routes, against low-level air attack.

Mechanically it is an S52 with the turret deleted. The extended rear cabin that the S52 used for weapons and ammunition stowage is what makes the S53 practical, because it holds the reload missiles. In place of the turret the ring carries an integral hatch cover with a periscope vision block, so the crew can keep watch closed down, and a pintle mounting for a vehicle variant of the Blowpipe/Javelin lightweight multiple launcher, LML(V) — a fit that later sources describe in terms of the Starburst close air-defence missile system as that weapon superseded its predecessors. The launcher's traverse head assembly, with a sealed bearing unit, drops over the pintle and has 40 degrees of traverse either side relative to the ring; the ring itself carries handgrips so the aimer can slew it round to the approximate target bearing and then track the target on the launcher. The whole installation is manually operated, with no powered traverse or fire-control system.

The launcher mounts three canistered missiles and uses the standard shoulder-launch aiming unit, clipped on as normal equipment rather than built into the vehicle — so the same aiming unit serves dismounted and mounted engagements. Six further missiles in their containers are stowed in racks on either side at the rear of the hull, with the aiming unit carried between those racks when travelling.

The S53 remains the thinnest-documented Series 5 variant. No customer, contract, delivery total or production date specific to it has been found in the sources consulted; Army Guide and the Shorland Site describe the equipment fit in detail but record no operator, and the Jane's-derived family entries list the S53 only as a member of the range. It is therefore recorded here as a marketed variant of confirmed configuration but unconfirmed service, and this record is left as a draft pending a documented order or delivery.
