Staggerwing`s question on radar.
Shipborne military naval radar is horizon limited and relies on sat link for enhanced range and altitude. Airborne radar, such as EWAC is the current fashion. The actual numbers are not on general display for obvious reasons, so there is not much more than just the usual theoretical data around. The only useful tool in the area is the Ozzie Jindalee Operational Radar Network, multistatic radar using OTH-B (OVER THE HORIZON ) with an official range of 1900miles.
Here is its coverage, near enough to the current search area.
