|Although not an F-16 weapon, I thought this was interesting. Navy has put out a contract for it for use in Iraq. Basically a de-tuned BLU-111 with less stuff in it for a smaller bang. It has some dead weight in it to keep the same weight as a 500lb 'er so it flys the same.
BLU-126/B The BLU-126/B LCDB (Low Collateral Damage Bomb) is a 225 kg (500 lb) class high-explosive bomb. It is externally identical to the BLU-111( )/B, but is filled with less explosives for a reduced fragmentation pattern blast radius. The LCDB was developed by the U.S. Navy for use in situations where friendly forces and/or civilians are close to the target. The BLU-126/B is ballistically equivalent to the BLU-111( )/B, and can therefore be used with the same LGB (GBU-12( )/B Paveway II) and GPS (GBU-38( )/B JDAM) guidance packages.

Anyway... interesting trivia.
