US Navy's new $4.4 billion sub is still broken

You'd think that by spending $4.4 billion on something, it would work... right? The US Navy has built its new destroyer, the USS Zumwalt, with an expensive receipt to cry over - and only weeks after it was officially commissioned, it has been put out of action.

The US Navy said it was their most technologically advanced destroyer, with hidden weapons and sharp angles that make it hard to spot on radar. Engineering problems persisted, and when the USS Zumwalt attempted to join with the US Third Fleet in San Diego, it only made it as far as the Panama Canal, reports Engadget.

The ammo for the $4.4 billion ship is also expensive, sitting at $800K per round, and with a purported 30 Zumwalts in development, the US Navy would be spending some big bank on these ships. The total cost for developing just three Zumwalts is already past $22 billion.
