Here’s why the Corps strapped a counter-drone system to the deck of a warship in the Suez Canal

Thank you, my friend CW5 Jack Cardwell for making us aware "U.S. Navy ships often have to traverse dangerous choke points that make them susceptible to attacks."
To be honest U.S. Navy ships for centuries have had to "traverse dangerous choke points."
In WWI, aircraft became both a capability useful to the navies. By WWII the aircraft carrier became the most capable offensive weapon for the surface navy vessels.
In WWII, aircraft became the gravest threat to Navy vessels as suicide kamikaze Baka bombs and other explosive laden fighter aircraft.
Armed speed boats [US PT, German E-boat in WWII] and this century Iranian speed boats in the Straits Of Hormuz have harassed US Navy vessels .

"To mitigate that risk, the Marine Corps often rolls out tactical vehicles on the ship’s deck to beef up security.
The Corps did just that on Jan. 12, when the Wasp-class amphibious assault ship Kearsarge, hauling Marines, sailors and Harriers embarked with the 22nd Marine Expeditionary Unit, or MEU, transited the Suez Canal.
But this time the Marines strapped down its latest toy, a new counter-drone system known as the Light Marine Air Defense Integrated System, or LMADIS. The system was actively scanning the sky for small drones that could pose a threat to the ship, according to Capt. Joshua Smith, a spokesman with the 22nd MEU.
The use of the small counter-drone system on the Navy ship highlights the military’s growing concern regarding the proliferation of drone technology and the threat it poses to even heavily armed American warships as they continue to operate in choke points and narrow waterways around the globe."

Radars have been known to pick up birds on their screens and yet we need a technology to pick up drones? Glad we have them and we are using ingenuity by utilizing LAV's for surface scanning for small boats. Of course I think it's about time to invest in new equipment if our warships have to rely on Marine Corps war vehicles for sea-surface warfare defense.

CW5 Jack Cardwell Who will invent a counter to the counter?
