Pyros (bomb)

The Pyros, previously referred to as the Small Tactical Munition , is a weapon developed by Raytheon, designed to be used by UCAVs.

History

Raytheon successfully conducted flight tests in October 2010, and it may be used to arm the AAI RQ-7 Shadow.
In July 2012, Raytheon claimed the STM could be "months" away from fielding.
In early August 2012, Raytheon renamed the munition Pyros and completed the first end-to-end test of the bomb.
The test validated the weapon's guidance modes, height-of-burst sensor, electronic safe and arm device, and multi-effects warhead.
On July 18, 2014, Raytheon conducted the first live-fire test of the Pyros. The munition targeted a simulated group of insurgents planting a roadside bomb and used its height-of-burst sensor to detonate several feet above the ground.

Design

The original model weighs, and originally had a warhead.
On April 18, 2011, Raytheon successfully tested a new warhead for the weapon.
Though lighter, the new warhead has a significantly improved blast-fragment capability.
Designed for low collateral damage, its lethal radius is only, with non-lethal effects extending further but lethality dropping dramatically.
Dropped from an altitude of, the Pyros takes 35–40 seconds to reach the ground.
