Marines Use Helium Balloons to Talk to Harrier Jump Jets Over Libya
The Marines debuted another new technology last week in the fight against Gadhafi’s forces when the 26th Marine Expeditionary Unit aboard the USS Kearsarge used a high-tech balloon to relay messages to the ship’s AV-8B Harrier jump jets flying strike missions over Libya, beyond the range of the ship’s transmitters.
Normally, the ship would have to pass messages to a nearby E-3 AWACS jet that would then send those messages along to the Harriers. However, the helium balloon-based Lofted Communications System carried aboard the Kearsarge fills that role without leaving the Marines reliant on an AWACS.
Here’s how it works; depending on how far the Marines need to send messages, they send up a tethered or untethered balloon carrying a communications relay device capable of passing radio messages and encrypted information hundreds of miles to the Harriers.
