HUNTSVILLE, Ala. (WHNT) – People around Redstone Arsenal may have noticed a thick plume of smoke coming from the southern part of the installation.  It was from a THAAD missile test.

Here is the release from Redstone’s public relations department:

Arsenal officials announced that a Terminal High-Altitude Area Defense – THAAD – missile round, will be tested at a range on the south side of the installation on October 25, between 7:00-9:00 a.m., weather conditions permitting. 

 Specifically, the test will verify the system’s compliance with the nation’s Insensitive Munitions law, which mandates that munitions be stable enough to withstand mechanical shocks, fire, and impact.

In the test a liquid fuel fire will validate that requirement. This test will produce a lot of smoke largely due to the JP-8 (11,000 gallons) required to create the necessary test environment. The plume will be seen in the southern most portion of Redstone Arsenal.

The operation usually takes about 45 minutes.
