Martime Facilities Security–Swimmer Defense

The Israelis are marketing a anti-swimmer sensor system that claims increased range, believed necessary because increased speed of swimmer delivery systems shortens reaction time.

“The AquaShield ER offers unprecedented detection ranges against all marine threats. The AquaShield ER passed rigorous sea trials achieving detection ranges of up to 3.5 kilometer for Swimmer Delivery Vehicle targets, 1.8 kilometers for Open Circuit Divers and 1.2 kilometers for divers using closed-circuit apparatus.”

Perhaps I am reading to much into this, but this capability may have played a part in intercepting five Hamas commandos who swam ashore in Israel recently as reported here.

I have been out of the loop for a long time, but I suspect the Coast Guard is still not integrated into a multiservice network capable of reacting to a terrorist incursion the way the Israelis reported did.

The Tammuz missile referred to in the report is in the same class as the Hellfire, but with a much longer range (25 km, that is more range than a WWII light cruiser). It has been previously referred to as the Spike NLOS (Non-line of Sight). Since they referred to this being mounted on an OPV rather than a corvette or missile boat, I suspect they are talking about it having been mounted on something relatively small, about the size of an 87 footer.

Port Security Barriers

Prompted by a recent incident in the waters off Gibraltar, between Royal Navy and police on one side and the Spanish Guardia Civil on the other, ThinkDefence has posted advertising and videos of a number of barrier systems. I’ve seen one of these deployed around aircraft carriers in San Diego.  All are claimed to be effective against at least small boats, some against swimmers or larger vessels. Much of the interest in these systems goes back to attack on the USS Cole in Yeman.
