3. Russian Sukhoi Su-35S Flanker-E fighter jet
Price tag – US$40 million to $65 million (estimated) per unit
The Sukhoi Su-35 is a single-seat with a twin-engine. These engines have thrust vectoring, allowing the aircraft to climb at a greater rate than its predecessor, the first Soviet-time Su-27. It’s a super maneuverable multirole fighter, designed by Sukhoi and built by Komsomolsk-on-Amur Aircraft Production Association (KnAAPO).
Su-35 Flanker-E cockpit
The cockpit has a central control column and is fitted with a Zvesda K-36D-3.5E zero-zero ejection seat which allows the pilot to eject at zero speed and at zero altitudes.
The aircraft has a quadruplex, digital fly-by-wire control developed by the Avionika Moscow Research and Production Complex JSC (MNPK Avionika).
The cockpit is fitted with two 230mmx305mm high-resolution MFI-35 liquid crystal displays with a multifunction control panel and a IKSh-1M head up display with a wide 20°x30° field of view.
The pilot has two VHF/UHF encrypted radio communications systems and a jam-resistant military data link system between squadron aircraft and between the aircraft and ground control. The navigation system is based on a digital map display with a strap down inertial navigation system and global positioning system.
Compared to the Su-27 design from which it is derived, the front fuselage diameter of the Su-35 has been increased to accommodate the larger 900mm-diameter antenna of the Irbis-E radar.
High-strength, low-weight, composite materials have been used for non-structural items such as the radomes, nose wheel, door and leading-edge flaps. Some of the fuselage structures are of carbon fiber and an aluminum-lithium alloy.
The aircraft has 12 hardpoints for carrying external weapons and stores.
Each wing has four hardpoints – one on the wingtip and three under-wing stations. There are two hardpoints on the underside of the fuselage on the centerline and one under each engine.
The aircraft’s air-to-air missiles can include the Vympel R-27 (Nato designation AA-10 Alamo), the Vympel radar-guided medium-range R-77 (AA-12 Adder) and the Vympel short-range infrared-guided R-73E (AA-11 Archer).
The aircraft’s air-to-surface missiles include the Molniya Kh-29 (AS-14 Kedge) tactical missiles, the Kh-31P (AS-17 Krypton) anti-radiation missiles and the long-range Kh-58UShE (AS-11 Kilter) anti-radiation missiles.
The Su-35 anti-ship missiles include Kh-31A, the long-range Kh-59MK (AS-18 Kazoo), the long-range Kalibr and the NPO Mashinostroenia heavy long-range Yakhont missile.
The Su-35 can be armed with a range of guided bombs, including the KAB-500Kr TV-guided bomb, KAB-500S-E satellite-guided bomb, LGB-250 laser-guided bomb, Kab-1500Kr TV-guided bomb and KAB-1500LG laser-guided bomb.
The aircraft can also be armed with 80mm, 122mm, 266mm and 420mm rockets.
The Gryazev-Shipunov 30mm GSh-30-1 gun is fitted in the starboard wing root with 150 rounds of ammunition.
The X-band multimode phased array Irbis-E radar is supplied by Tikhomirov Scientific-Research Institute of Instrument Design (NIIP), based in Zhukovsky. Irbis-E is a high-performance radar designed for the Su-35 aircraft.
The 900mm passive phased array antenna is mounted on a hydraulic actuator for mechanical steering. The electronic steering provides azimuthal and elevation coverage of 60°. With both mechanical and electronic scanning, the coverage is 120°.
The radar can detect low-observable and stealth aircraft, unmanned air vehicles and missiles with a radar cross section of 0.01m² at ranges to 90km. Radar modes include air-to-air, air-to-ground, air-to-sea, mapping, Doppler beam and synthetic aperture radar modes. It can detect and track up to 30 airborne targets with a radar cross section (RCS) of 3m² at ranges of 400km using track-while-scan mode.
Infrared search and track
The infrared search and track fire control system, OLS-35 IRST, includes an infrared sensor, laser rangefinder, target designator and television camera. The accuracy of the laser rangefinder is 5m CEP (circular error probability), to a maximum range of 20km against airborne targets and 30km against ground targets. The OLS-35 is a high-performance system with ±90° azimuthal and +60°/-15° elevation coverage.
The system’s acquisition range against a non-afterburning target is 50km forwards and 90km rearward. The Su-35 can also be fitted with a UOMZ Sapsan targeting and laser designation pod.
The aircraft’s electronic warfare suite includes a radar warning system, radar jammer, co-operative radar jamming system, missile approach warner, laser warner and chaff and flares dispenser.
The aircraft is powered by two Sturn / UFA AL-31F 117S turbofan engines with thrust-vectoring nozzle control, each supplying 86.3kN thrust or 142.2kN with afterburn. The engines were developed jointly by Sukhoi, Saturn, and UMPO.
The aircraft can fly at a maximum speed of 2,390km/h. The normal and ferry ranges of the aircraft are 3,600km and 4,200km respectively. The maximum altitude is 18,000m. The Su-35 weighs around 18,400kg and the maximum take-off weight is 34,500kg.

The technical team from the Department of National Defense (DND) will attend Russia’s International Military-Technical Forum “Army-2016” at the Kubinka Airfield in Moscow, Russia to check and possibly acquire a Russian-made fighter aircraft that can simultaneously perform multiple role missions that can be used as a multirole fighter aircraft for the Philippines. – JCE.
