The Thunderbolt 3 specification says it's backward compatible with the older Thunderbolt 2. But more than one manufacturer has said that its Thunderbolt 3 peripherals are not compatible. The reason seems to be twofold; first, some early USB-C controller chips seem to have a backward compatibility issue; and second, a Thunderbolt 3 peripheral, while using a Thunderbolt 3 port, isn't actually using the Thunderbolt data channels; instead, it's making the connection over the USB 3.1 Gen 2 channels.

The multirole F/A-18 Hornet fighter was designed for both air-to-air and air-to-ground missions and led to the F/A-18 E/F Super Hornet and the EA-18G Growler. The McDonnell Douglas F/A-18 Hornet is a twin-engine, supersonic, all-weather, carrier-capable, multirole combat jet, designed as both a fighter and attack.
