Paveway IV Booster

207

I have yet to cover the Paveway IV Precision Guided Bomb in the Complex Weapon Series but this piece of contract news is worth sharing.

Title attributed to the contract

Design and development of a fully IM Compliant Booster for the Paveway IV Weapon System.

Value: 2 300 000 GBP

The Secretary of State for Defence (the Authority) acting through International Guns, Missiles and Rockets Project Team of Defence Equipment and Support proposes to award a Contract to Thales Missile Electronics Ltd for the design, development and optional qualification of an Insensitive Munition Compliant Aurora Fuze Booster for the Paveway IV weapon system.

A XI(B) Sqn Tornado GR4 training for deployment to Afghanistan. Pictured here on 12 October 2012 is a Tornado GR4 aircraft as it undertakes a training sortie over the North West of England. The Tornado from IX(B) Squardon is preparing for deployed operations over Afghanistan in the near future.

The Tornado GR4 is a variable geometry, two-seat, day or night, all-weather attack aircraft capable of delivering a wide variety of weapons. Powered by two Rolls-Royce RB 199 Mk 103 turbofan engines, the GR4 is capable of low-level supersonic flight and can sustain a high subsonic cruise speed.

The GR4 typically carries up to a maximum of 5 Paveway IV smart weapons or 2 Stormshadow cruise missiles but can be configured with various weapons, targeting pods and reconnaissance pods simultaneously including the Dual Mode Seeker (DMS) Brimstone, ALARM Mk2 missile, Litening III and the Reconnaissance Airborne Pod TORnado (RAPTOR).

The Tornado GR4 is a world leader in the specialised field of all-weather, day and night tactical reconnaissance. The RAPTOR pod is one of the most advanced reconnaissance sensors in the world and greatly increases the effectiveness of the aircraft in the reconnaissance role. Its introduction into service gave the GR4 the ability to transmit real-time, Long Range Oblique Photography (LOROP) to commanders or to view this in cockpit during a mission. The stand-off range of the sensors also allows the aircraft to remain outside heavily defended areas, thus minimising the aircraft’s exposure to enemy air-defence systems. Additional capability in the Non-Traditional Intelligence Surveillance and Reconnaissance (NTISR) role is provided by the Litening III RD and the use of the ROVER data link for providing tactical operators with real time Full Motion Video (FMV) in the battle space. 

The Tornado GR4 is now equipped with the Storm Shadow missile and 2 variants of the Brimstone missile, including the most advanced DMS variant.

Paveway IV laser guided bombs can be seen on the outermost pylon underneath the wings. Not an expert on these things but I suspect a Fuze Booster is not a booster that we might think of (one that extends the range of the bomb) The Aurora Fuze is the clever bit at the back of the bomb that provides the ability to air burst, explode on contact or after penetrating a target.

Anyone have the first clue what it actually is?

Seems to possibly be a case of a replacement for the banned Tetryl explosive with and IM (Insensitve Munition) in UN HD class 5 explosive safety class – see

In this case I think booster in a fuze ‘boosts’ the very small ‘explosion’ of the detonator into something useful, although I think the more usual UK term is ‘magazine’. However, this isn’t really Thales area in UK, BAe are the explosive experts and I’d have expected some form of their ROWANEX for this.

I did not answer the question but this article makes it quite clear http://en.wikipedia.org/wiki/Explosive_booster
it was quite frequent with a number of Naval large HE capacity to have train of charges such as primary and secondary boosters or Gaines if I remember correctley to set of the fuzing system to activate/setof the main detonation.

People might find it more familiar if you called it a primer. For those of you who used det cord before, it’s that blob you tie at every meter(?) or so to boost the burn/explosion rate of the det cord so that is doesn’t die out before the next meter. Think there was also an ad hoc stand in where if you ran out of primers, you tie a knot in the det cord so that the knot blows up at once and boosts the explosion on its way.

So basically, this “booster” pushes a small detonation that helps cause a bigger detonation from the parent explosive. Explosion booster, not propulsion.
