A top Pentagon official responsible for purchasing arms for America's defense stockpile has expressed 'shock' at the increasingly sophisticated arsenal possessed by Yemen's Houthis.

Under Secretary of Defense for Acquisition and Sustainment Bill LaPlante spoke at an event hosted by Axios on Wednesday, where he said that Houthis are displaying and deploying advanced weaponry, especially missiles that "can do things that are just amazing."

He described that Houthis "are getting scary" in terms of their capability on display for more than a year in the Red Sea, where they've gone to war against Israeli and international shipping.

"I'm an engineer and a physicist, and I've been around missiles my whole career," LaPlante said before the summit, called the "Future of Defense" in Washington, DC.

"What I've seen of what the Houthis have done in the last six months is something that — I'm just shocked."

Among the surprisingly advanced capabilities include anti-ship ballistic missiles. Analysts have widely asserted that without doubt Iran is directly supplying these and other capabilities.

The Houthis have also routinely scored direct hits on commercial shipping vessels with both aerial and drone boats.

The Shia group has also claimed many times to have scored hits on US, UK, and other allied warships; however, the US has kept a tight lid on the extent of this, or actual damage, perhaps wishing to not give the Houthis a propaganda win.

According to the latest attacks on US warships via an announcement this week from the Pentagon:

Houthi forces attacked two American destroyers with drones and missiles as the ships transited the Bab el-Mandeb Strait entering the Gulf of Aden on Monday, a Pentagon spokesman said today.

The Houthis launched at least eight one-way uncrewed aerial systems, five anti-ship ballistic missiles and three anti-ship cruise missiles at USS Spruance (DDG-111) and USS Stockdale (DDG-106), which engaged all the projectiles, Pentagon Press Secretary Maj. Gen. Patrick Ryder told reporters on Tuesday. U.S. Central Command has not yet issued a statement.

The Pentagon says that the warships were not damaged in the attack, which contradicts the account of Houthi spokesman Brig. Gen. Yahya Sare’e, who quickly claimed the attack on the pair of destroyers was successful.

The past year has seen a number of videos like the below showing destruction of large tankers off Yemen's coast:

The enduring conflict in the Red Sea has been widely acknowledged as the biggest naval battle that US forces have been engaged in since World War II. Several US and Israeli airstrikes have hit Houthi positions hard over the last months, but this appears to have done little to erode Houthi capabilities.
