GPS Guided Munitions

Featured Replies

Is the "accuracy bonus" discussed in 6.3.4.2.4 that a weapon, such as

JDAM, is resolved on the Dive Bomb Table (Low or Medium depending upon

the altitude it is launched)?

 

Per DaveS (msg #3689) on the Admiralty Trilogy Yahoo Group:

 

"If a GPS guided weapon is used against a nonmoving target it gets the bonus

and you would use the Low or Medium altitude dive bombing tables as

appropriate.

 

If the target is moving and the weapon does not have terminal guidance, treat

it as a dumb bomb (if it does have terminal guidance, treat it as a PGM)."

 

 

Short answer: yes, the GPS accuracy bonus is resolving it on the respective dive bomb tables.

In the April 2003 issue of The Naval Sitrep

 

If directed versus land targets:

 

In further reading about H4.1 attacks on land targets by naval and

air platforms, I came across the short article titled "Land Attack

Missiles in Harpoon" and its accompanying Land Target Attack Table (Page 24).

 

Increases the GPS guided munitions to a much more appropriate pH (IMHO).

The H4.1 rule as originally stated was made at a time when GPS guided munitions (i.e. JDAM) were still in their infancy. JDAM has turned out to be even more accurate than was expected, and the SITREP from 2003 certainly addresses this. In fact, I think the rule will have to be further adjusted (again, upward) as a result of experiences with using JDAM in Iraq and Afghanistan, and the eventual addition of a moving target capability.

It's huge. I would have thought that it would have been addressed in the latest errata, which is dated later than the issue of the SITREP.

 

Either way, I know it know. Good Gaming. B)
