fighter/attack version for the Spanish Air and Space Force, the E is for España (Spain in Spanish). The Spanish Air and Space Force designation is C.15, the C being for Caza (fighter aircraft in Spanish, lit. hunt). They were first upgraded to the EF-18A+ version in 1992, this included pylons, computing and electronic systems in the F/A-18C standard. The Spanish Air and Space Force acquired licenses and locally developed many upgrades to the Operating Flying Program (OFP), i.e. the software that controls the aircraft computers. They were the first hornets in the world capable of using the AGM-65 Maverick air to ground missile, and the first air force to use it against naval targets. From 2004 to 2013 they were locally upgraded by EADS CASA and Indra Sistemas in the Mid-life Upgrade (MLU) program, with better avionics, data buses, TPAC, data presentation (bigger color and touch displays similar to the F/A-18E Super Hornet), navigation, communications (radios), software and ECM suit. The AN/APG-65 radar was upgraded to the V3 version and the aircraft also received the AL-400 Radar Warning Receiver and the ASQ-600 emission detector and were certified to operate with Iris-T, Meteor, GBU-48 and Taurus. This also included a thorough structural and engine revision and overhaul, and a new paint job for a few units. This version is locally known as EF-18MLU/C.15M and is considered superior to the US F/A-18C version. EF-18B: Two-seat training version for the Spanish Air and Space Force. The Spanish Air and Space Force designation is CE.15. The E is for Entrenamiento, meaning training in Spanish. They were first upgraded to the EF-18B+ version in 1992. KAF-18 Hornet KAF-18C: Single-seat fighter/attack version for the Kuwait Air Force KAF-18D: Two-seat training version for the Kuwait Air Force F-18C/D Hornet The Finnish Air Force uses F/A-18C/D Hornets, with a Finland-specific mid-life update. The first seven Hornets (D models) were produced by McDonnell Douglas. The 57 single-seat F-18C model units were assembled by Patria in Finland. These variants were delivered without air-to-ground capability so the letter A was dropped from the name. They were later upgraded to carry air-to-ground weaponry. F-18C/D Hornet Switzerland uses F-18C/D, later Swiss specific mid-life update. The Swiss F-18s had no ground attack capability originally, until hardware was retrofitted.
