[sci.military] It's GBU, not CBU.

I originally asked about "CBU-15"s used on the oil manifolds that were
supplying the oil slick in the Gulf.  When I got it straight I received
the following information.
-----------------------------------------------------------------------
Data extracted from the Air Force Magazine, May 1990.

The GBU-15 is essentially a 2000 lb. Mk-84 iron bomb fitted with
cruciformwings and a guidance system.  The target detecting device
is carried on thefront of the warhead.  The control module, with auto-
pilot and data link, attaches to the rear.  Two modes of attack are
available.  In direct attack,the weapon is locked on to the target
before launch and flies a near line-of-site profile to impact.  In
indirect mode, the seeker can be locked on to the target after launch,
 or the WSO can "fly" the weapon manually to impact, using guidance
updates provided through the data link.  The GBU-15(V)1 is a TV guided
variant; the GBU-15(V)2 is an imaging infrared (IIR) version.  Note that
the "GBU" stands for "Glide Bomb Unit", not "Guided" -- and it is not
powered.  There is a powered variant of this unit being developed called
the AGM-130.

By the way, the most common CBU (Cluster Bomb Unit) is the Rockeye.  I don't
remember its numerical designation.
