A gun too expensive to shoot

Of course, it comes from the Defense Department.

The new 155mm projectiles for the USS Zumwalt's main battery are too expensive to fire.  Cost overruns increased the price tag by a factor of 10, so that each round was $800,000 and the contract was canceled.

The Navy is looking to replace it with either the Army's Excalibur system or a rail gun.  No word on whether everyone in the Navy's Project Management Office has been reassigned to deck swabbing duty.
