McDonnell Douglas F-18 Hornet C/D http://en.wikipedia.org/wiki/F/A-18_Hornet
The F/A-18C and D models are the result of a block upgrade in 1987 incorporating upgraded radar, avionics, and the capacity to carry new missiles such as the AIM-120 AMRAAM air-to-air missile and AGM-65 Maverick and AGM-84 Harpoon air-to-surface missiles. Other upgrades include the Martin-Baker NACES (Navy Aircrew Common Ejection Seat), and a self-protection jammer. A synthetic aperture ground mapping radar enables the pilot to locate targets in poor visibility conditions. C and D models delivered since 1989 also include an improved night attack capability, consisting of the Hughes AN/AAR-50 thermal navigation pod, the Loral AN/AAS-38 NITE Hawk FLIR (forward looking infrared array) targeting pod, night vision goggles, and two full-color (previously monochrome) MFDs and a color moving map
General Dynamics F-16 Fighting Falcon C/D http://en.wikipedia.org/wiki/F-16_Fighting_Falcon
The F-16C (single seat) and F-16D (two seat) variants entered production in 1984. The first C/D version was the Block 25 with improved cockpit avionics and radar which added all-weather capability with beyond-visual-range (BVR) AIM-7 and AIM-120 air-air missiles.
Dassault Mirage 2000-5 http://en.wikipedia.org/wiki/Mirage_2000-5
Improvements included the Thales TV/CT CLDP laser designator pod as well as the Thales multimode RDY (Radar Doppler Multitarget), which allows detection of up to 24 targets and the ability to simultaneously track 8 threats while guiding 4 MICA missiles to different targets. Updates to defensive systems included the ICMS 2 countermeasures suite and the Samir DDM missile warning system. ICMS 2 incorporates a receiver and associated signal processing system in the nose for detecting hostile missile command data links, and can be interfaced to a new programmable mission-planning and post-mission analysis ground system. Avionics were also updated, using a new Night vision-compatible glass cockpit layout borrowed from the Rafale, a dual-linked wide-angle Head-up display, and HOTAS controls. The Mirage 2000-5 can also carry the oversized drop tanks developed for the Mirage 2000N, greatly extending its range
Saab JAS 39 Gripen A/B http://en.wikipedia.org/wiki/JAS_39_Gripen
Batch Three aircraft possess more powerful and updated avionics, in-flight refuelling capability with the provisions of retractable probes on the aircraft's starboard side, and an on-board oxygen-generating system for longer missions.
The Gripen uses the modern PS-05/A pulse-doppler X-band radar, developed by Ericsson and GEC-Marconi, which is based on the latter's advanced Blue Vixen radar for the Sea Harrier (which inspired the Eurofighter's CAPTOR radar as well).[39] The radar is capable of detecting, locating and identifying targets 120 km (74 mi) away,[40] and automatically tracking multiple targets in the upper and lower spheres, on the ground and sea or in the air, in all weather conditions. It can guide several air to air missiles at beyond visual range to multiple targets simultaneously.
Mikoyan MiG-29 http://en.wikipedia.org/wiki/Mig-29
The baseline MiG-29B has a Phazotron RLPK-29 (Radiolokatsyonnui Pritselnui Kompleks) radar fire control system (FCS) which includes the N019 (Sapfir 29; NATO: 'Slot Back') look-down/shoot-down coherent pulse-Doppler radar and the Ts100.02-02 digital computer. Tracking range against a fighter-sized target was only about 70 km (38 nmi) in the frontal aspect and 35 km (19 nmi) in the rear aspect. Range against bomber-sized targets was roughly double. Ten targets could be displayed in search mode, but the radar had to lock onto a single target for semi-active homing (SARH). The MiG-29 was not able to reliably utilize the new Vympel R-27R (NATO: AA-10 "Alamo") long-range SARH missile at its maximum ranges.
