The 30mm Solution
The Strategy Page ^ | 7/4/2010 | The Strategy Page

Posted on 07/05/2010 6:46:12 PM PDT by ErnstStavroBlofeld

U.S. Army has established a second source (General Dynamics) for 30mm cannon ammunition. This is to insure there are no interruptions in deliveries, and some competition when it comes to production quality and price. The U.S. Army is using over half a million 30mm cannon rounds a year for its AH-64 Apache helicopter gunships. Each round costs over $100. In Iraq and Afghanistan, the most accurate cannon fire comes from the 30mm autocannon on the AH-64 helicopter, and such support is very popular. This is partly because of the increased emphasis on reducing civilian casualties. During the heaviest combat in Iraq (2006-7), about a quarter of the army's 24 AH-64 battalion (18 Apaches each) were in Iraq or Afghanistan. But now these gunships are being shifted from Iraq to Afghanistan. .

The 127 pound M230 30mm cannon fires about ten rounds a second, and AH-64s normally carry 1,200 rounds. The most common round used is the HEDP (high explosive dual purpose), meaning that the round not only penetrates up to 50mm of armor, but generates fragments that kill or wound personnel within four meters (12 feet) of detonation. Each round carries .76 ounces (22 grams) of explosives, is 7.8 inches (20 cm) long and weighs 11.8 ounces (339 grams), while the projectile weighs half a pound (229 grams). A direct hit on a person is fatal, and messy.

Effective range of the 30mm cannon is about 4,000 meters. Time in flight to 3,000 meters is 12 seconds. The fire control system takes care of all the necessary aiming adjustments for long range shots. The Apache also has a red-dot laser indicator for the 30mm cannon. This reduces friendly fire incidents.

12 seconds to go 3000 meters? It could fall faster than that.

AH-64s normally carry 1,200 rounds...at $100/round

I'd love to take off with $120,000 of ammo aboard.

Not as beautiful as the thought of that “Oh, Sh*t,” moment when a jihadi hears the distant sound of chopper blades and looks down to see that red laser painting his chest.

I kind of hate to see them spend $100 per round to kill a few jihadis, but if brings more of our guys home alive and in one piece, I’m all for it.

You beat to my calculator. 833 fps is subsonic but it does get there. Plus, to paraphrase one of the aliens in the film Galaxy Quest, "and it explodes!"

That's because my iaito is lighter than your katana, thus faster (but less dangerous ;-))

Typical gov't contractor + brainless gov't procurement policies + basically no project management...gee, I dunno, it looks pretty straightforward to me.

I am reading a great book by author Ed Macy, retired British Apache Helicopter pilot as he talks about his time in Afghanistan.
