How much is too much for the US Navy to spend on bullets (projectiles) for its guns?

Main article: Advanced Gun System

The Advanced Gun System is a 155 mm naval gun, two of which are installed in each ship. This system consists of an advanced 155 mm gun and its Long Range Land Attack Projectile (LRLAP).[67] This projectile is a rocket with a warhead fired from the AGS gun; the warhead has an 11 kg / 24 lb bursting charge and has a circular error of probability of 50 meters. This weapon system has a range of 83 nautical miles (154 km);[Note 1][53] the fully automated storage system has room for up to 750 rounds.[64][67] The barrel is water-cooled to prevent overheating and allows a rate of fire of 10 rounds per minute per gun. Using a Multiple Rounds Simultaneous Impact (MRSI) firing tactic the combined firepower from a pair of turrets gives each Zumwalt-class destroyer initial strike firepower equivalent to 12 conventional M198 field guns.[68][69] To provide sufficient stability to fire these guns, the Zumwalts use ballast tanks to lower themselves into the water.[70] In November 2016, the Navy moved to cancel procurement of the LRLAP, citing per-shell cost increases to $800,000–$1 million resulting from trimming of total ship numbers of the class. The Navy is monitoring research on alternative munitions, but since the AGS was tailor-made to use the LRLAP, modifications will be needed to accept different shells, which is unlikely to happen by the time the first Zumwalt vessel enters operational service in 2018, leaving it unable to fulfill the naval gunfire support role it was designed for.[71][72][73]

Missile = rocket with warhead

Yeah, I wondered about that, too. But they are fired from a gun. That class off DDG also carries Tomahawk and Sparrow missiles. Quite a cool looking ship. I would love to take a tour on one to compare it to the three ships I was on. I appears Kittigate was correct. This post was edited by Element 99 at March 15, 2019 5:29 PM MDT

Allegedly ... the Zumwalt class ships will be upgraded with railguns.

Both China and America have naval ships out testing railguns, currently.

Think of this, though.
China with a land-based railgun network, and their stance on the China Sea.
The US Navy is nothing but sitting ducks.

Now expand that to a Chinese lunar base, which they have stated as their goal.

That would be awesome.

Zumwalt class, when it partially submerges has the radar profile of a fishing boat.

One of our warships is visiting his country. Why are so many foreigners concerned about our politics?

I ask that question on this site often.

US has interests of some sort in just about every country in the world and even the moon and Mars. We's just a bit curious what's makin' you all tick.
