Here;s a new impression of the F-16IN from the latest issue of Lockheed Martin's Code One magazine. Note the deployable refuelling boom housed in the conformal fuel tank. For the article:
"This aircraft will feature a refueling boom that retracts from the right conformal fuel tank. The boom allows the F-16IN to operate with India Air Force probe-and-drogue style aerial refueling systems similar to those used by the US Navy. The refueling boom is now being flight tested in Fort Worth."
Several other systems distinguish the F-16IN from the Block 60, including an electronic warfare system and radar modes tailored for India, dragchute, datalink, satellite communication, and a helmet-mounted cueing system. The F-16IN will carry the Sniper targeting pod as well."
