Overview
14 November 2012: The US government reveals plan to equip Yemen with 25 light observation aircraft for intelligence, surveillance, and reconnaissance (ISR) work.
A request for information (RFI) issued by the US Naval Air Systems Command (NAVAIR) calls for a light aircraft for the ISR role that will also be capable of providing in-country pilot training.
In a list of requirements, NAVAIR has set out some very specific criteria for the aircraft it is looking to field. These criteria state that it must be a commercial off-the-shelf pusher-propeller piston-engine aircraft of high-wing monoplane and tail dragger design. It should have side-by-side seating for two crew members, must be capable of operating out of austere locations, and should be sea transportable in a 40-ft ISO shipping container.

Airborne ISR LOS Datalink Ground Station
The EnerLinks Tracking Antenna System (ETAS) is a rugged, portable, and integrated high-gain antenna system that enhances the range performance of the EnerLinksIII™ full-duplex digital ISR data link. By adding the ETAS to your system, line-of-sight (LOS) range at 11 Mbps can exceed 100 nautical miles. The ETAS is packaged in three rugged cases that can be stowed in the back of a HMMVVV and deployed in less than five minutes. Automatic Switching For Continuous UAS Link PerformanceThere is no need for an additional, dedicated tracking unit because all tracking algorithms reside in the EnerLinksIII Ground Modem Transceiver (GMT). A 24-inch parabolic reflector antenna provides a constant link margin with frequency, and for close range where the UAS angular velocity is high, the system automatically switches to an integrated omni antenna for continuous link performance. Downlink switching uses the diversity combining feature of the EnerLinksIII GMT so that there is no loss of downlink video or data during switching. The ETAS is configurable for L-/S-, or C-band.
