The U.S. Navy commissioned the USS Zumwalt, its most technologically advanced warship yet, back in October.
The ship's centerpiece is the Long Range Land-Attack Projectile, the "most accurate and longest-range guided projectile" in Navy history.
But each round costs up to $1 million, USNI News reports. The Navy originally planned to build 32 Zumwalt-class ships, but budget cuts reduced that total to just three. And that meant the cost for each of those special projectiles went up -- way up.
"We were going to buy thousands of these rounds. But quantities of ships killed the affordable round," a Navy official told Defense News.
These ships aren't cheap
These ships aren't exactly cheap themselves. Each Zumwalt-class ship (the USS Michael Monsoor and USS Lyndon B. Johnson are on the way) costs about $4 billion to build.
The Navy is looking for alternative rounds for its Advanced Gun Systems. But it plans to incorporate the Zumwalt into its fleet by 2018, and it may not find a replacement in time. And the barrel was specifically designed for the LRLAP ammo, Rear Adm. Jim Downey told USNI News.
