The F-5 Tiger II, a single-seat twin-engined supersonic fighter aircraft, was developed by Northrop Grumman, US. The aircraft took its maiden flight on 11 August 1972 and entered into service in 1975. It is the upgraded version of the F-5A Freedom fighter aircraft developed by Northrop Grumman in early 1959.

The production of F-5A-21 began in 1970 by Northrop Grumman and at the same time the aircraft was renamed ‘F-5E Tiger II’. The avionics of the F-5E Tiger II are more sophisticated compared to the earlier version F-5A aircraft. It rolled out from production in 1987 and since then has undergone various upgrades to compete with changing combat environments.
The ”’Northrop F-5A and F-5B Freedom Fighter”’ and the ”’F-5E and F-5F Tiger II”’ are part of a supersonic+ light fighter+ family, initially designed in the late 1950s by Northrop Corporation+. Being smaller and simpler than contemporaries such as the McDonnell Douglas F-4 Phantom II+, the F-5 cost less to both procure and operate, making it a popular export aircraft. The F-5 started life as a privately funded light fighter program by Northrop in the 1950s. The design team wrapped a small, highly aerodynamic fighter around two compact and high-thrust General Electric J85+ engines, focusing on performance and low cost of maintenance. Though primarily designed for the day air superiority role, the aircraft is also a capable ground-attack platform. The F-5A entered service in the early 1960s. During the Cold War+, over 800 were produced through 1972 for U.S. allies. Though the USAF had no acknowledged need for a light fighter, it did procure roughly 1,200 Northrop T-38 Talon+ trainer aircraft, which were directly based on the F-5A. Source @datab.us
The aircraft costs are low and can be easily maintained compared to the F-15 and F-16 aircraft. It was used in the Cold War by the US Air Force (USAF) for training and war purposes. The aircraft can accommodate a single pilot.
The advanced aircraft features a single-seat cockpit equipped with number of electronic systems, namely automatic flight control systems (AFCS), head-up display (HUD) and other auxiliary equipment.

F-5E Tiger II armaments
The F-5E Tiger II is armed with two 20mm pontiac M39A2 cannons on either side of the nose. The M39A2 is a single-barrelled automatic cannon and can fire munitions at the rate of 1,500rpm. The aircraft features seven hard-points – two under the wing tip, four under the two wings, and one under the fuselage pylon station.
20mm pontiac M39A2 cannon
The M39 was developed by the Springfield Armory, based on the World War II–era design of the German Mauser Mauser MG 213, a 20 mm (and 30 mm) cannon developed for the Luftwaffe, which did not see combat use. The same design inspired the British ADEN cannon and the French DEFA 550, but American designers chose a smaller 20 mm round to increase the weapon’s rate of fire and muzzle velocity at the expense of hitting power. The M39 -originally known as the T160 – was tested on modified F-86Fs in Korea.
The M39A2 was introduced in 1964 and selected for the F-5E Tiger II.
In the M39A3, a five-chamber cylinder revolved about an axis parallel to the single gun bore. The weapon was gas-operated and fired from the six-o’clock position at a rate of 1,500 rounds per minute with a muzzle velocity of 3,300 feet per second. Source @wiki.scramble.nl

Four AIM-9 Sidewinder air-to-air missiles and two AGM-65 Mavericks air-to-surface missiles as well as rockets are mounted on the seven hard points. The aircraft is also armed with unguided iron bombs, CBU-24/49/52/58 cluster bomb munitions, napalm bomb canisters and M129 leaflet bombs.
The AIM-9B used a fragmentation warhead triggered by a passive infrared proximity fuse. The Thiokol Mk.17 solid propellant rocket delivered 8,200 lb-sec of impulse with a burn duration of 2.2 seconds.
While by modern standards the AIM-9B is a very limited weapon, it had no serious competitors in its day and was soon adopted by the USAF and NATO as a standard weapon, with no less than 40,000 guidance units built by Ford Aerospace, the prime contractor. The RAAF also adopted the missile, fitting it to the CAC Avon-Sabre, and subsequently the Mirage.
NATO rounds were mainly built by West Germany’s FGW, who evolved an improved subtype designated the AIM-9B-FGW Mod.2. This AIM-9B used solid state electronics, carbon dioxide seeker cooling, a new nose dome and better optical filtering, the latter providing for much better seeker sensitivity. Source @ausairpower.net
Later AIM-9 versions
The missile’s main components are an infrared homing guidance section, an active optical target detector, a high-explosive warhead, and a rocket motor.
The infrared guidance head enables the missile to home on target aircraft engine exhaust. An infrared unit costs less than other types of guidance systems, and can be used in day/night and electronic countermeasures conditions. The infrared seeker also permits the pilot to launch the missile, then leave the area or take evasive action while the missile guides itself to the target.

GM-65 Mavericks air-to-surface missile
The AGM-65 Maverick is a tactical, air-to-surface guided missile designed for close air support, interdiction and defense suppression mission. It provides stand-off capability and high probability of strike against a wide range of tactical targets, including armor, air defenses, ships, transportation equipment and fuel storage facilities.
The Maverick variants include electro-optical/television (A and B), imaging infrared (D, F, and G), or laser guidance (E). The Air Force developed the Maverick, and the Navy procured the imaging infrared and the laser guided versions. The AGM-65 has two types of warheads, one with a contact fuse in the nose, the other a heavyweight warhead with a delayed fuse, which penetrates the target with its kinetic energy before firing. The latter is very effective against large, hard targets. The propulsion system for both types is a solid-rocket motor behind the warhead. Source @fas.org
CBU-24/49/52/58 cluster bomb munitions
Regardless of its type or purpose, dropped ordnance is dispensed or dropped from an aircraft. Dropped ordnance is divided into three subgroups: bombs; dispensers, which contain submunitions; and submunitions.
Dispensers may be classified as another type of dropped ordnance. Like bombs, they are carried by aircraft. Their payload, however, is smaller ordnance called submunitions. Dispensers come in a variety of shapes and sizes depending on the payload inside. Some dispensers are reusable, and some are one-time-use items.
Dropped dispensers fall away from the aircraft and are stabilized in flight by fin assemblies. Dropped dispensers may be in one piece or in multiple pieces. All dropped dispensers use either mechanical time or proximity fuzing. These fuzes allow the payload to be dispersed at a predetermined height above the target. Multiple-piece dispensers open up and disperse their payload when the fuze functions. Single-piece dispensers eject their payload out of ports or holes in the body when the fuze functions.
Submunitions are classified as either bomblets, grenades, or mines. They are small explosive-filled or chemical-filled items designed for saturation coverage of a large area. They may be antipersonnel (APERS), antimateriel (AMAT), antitank (AT), dual-purpose (DP), incendiary, or chemical. Submunitions may be spread by dispensers, missiles, rockets, or projectiles. Each of these delivery systems disperses its payload of submunitions while still in flight, and the submunitions drop over the target. On the battlefield, submunitions are widely used in both offensive and defensive missions.
Submunitions are used to destroy an enemy in place (impact) or to slow or prevent enemy movement away from or through an area (area denial). Impact submunitions go off when they hit the ground. Area-denial submunitions, including FASCAM, have a limited active life and self-destruct after their active life has expired. The major difference between scatterable mines and placed mines is that the scatterable mines land on the surface and can be seen. Placed mines may be hidden or buried under the ground and usually cannot be seen. Source @fas.org

Napalm bomb canisters
The containers of napalm bomber are very light and fabricated of aluminum, with a capacity for about 75 gallons of combustible gel. They lack stabilizing fins, and consequently acquire a tumbling motion on being dropped that contributes to the scattering of the combustible gel over a wide area.
Napalm is a mixture of benzene (21%), gasoline (33%), and polystyrene (46%). Benzene is a normal component of gasoline (about 2%). The gasoline used in napalm is the same leaded or unleaded gas that is used in automobiles. Source @fas.org
M129E1/E2 Leaflet Bomb
The M129 is capable of holding approximately 60,000 to 80,000 leaflets and is dropped from fixed wing aircraft including B-52s, F-16s, F-18s and A-6s. The bombs explode at a lower altitude through the use of a timer allowing the rolled leaflets to be released and scattered. Source @psywarrior.com

The avionics equipped in the aircraft include an inertial navigation system (INS), tactical air navigation (TACN) system, global positioning system (GPS), electronic counter measures (ECM), and hand on throttle and stick (HOTAS) system.
F-5 Tiger II radar
The F-5 Tiger II was initially equipped with an AN/APQ-153 radar. In all the upgraded variants produced later, the Emerson AN/APQ-159 radar was installed. The aircraft comprises an air-to-air fire control radar system and a lead computing gunsight.

The AIM-9P, an improved version of the J model, has greater engagement boundaries, enabling it to be launched farther from the target. The more maneuverable P model also incorporated improved solid-state electronics that increased reliability and maintainability. Deliveries began in 1978.
The AIM-9P-1 has an active optical target detector instead of the infrared influence fuze; the AIM-9P-2 added a reduced-smoke motor. The most recently developed version, the AIM-9P-3, combined both the active optical target detector and the reduced-smoke motor. It also has added mechanical strengthening to the warhead as well as the guidance and control section. The improved warhead uses new explosive material that is less sensitive to high temperature and has a longer shelf life.
The AIM-9M, currently the only operational variant, has the all-aspect capability of the L model, but provides all-around higher performance. The M model has improved defense against infrared countermeasures, enhanced background discrimination capability, and a reduced-smoke rocket motor. These modifications increase ability to locate and lock-on a target and decrease the missile’s chances for detection. Deliveries of the M model began in 1983. Source @fas.org

AGM-45 Shrike anti-radar missiles
The AGM-45 SHRIKE series weapon system is a passive air-to-ground missile whose mission is to home on and destroy or suppress radiating radar transmitters, directing both ground antiaircraft fire and surface-to-air missiles. The system consists of an AGM-45 guided missile, AERO-5A/B or LAU-118 launcher, and a launch aircraft configured with SHRIKE-unique avionics and a target identification acquisition system. The AGM-45 SHRIKE guided missile is composed of four major sections; guidance, warhead, control, and rocket motor. Along with the wing and fin assemblies, the sections make up the all-up-round missile. Several missile versions have been developed and produced to home on certain types of enemy radar transmitters. Each version consists of a guidance section specially developed and tuned to a specific frequency range unique to an individual threat radar. The AERO-5B-1 and LAU-118 series rail launchers are used to launch the SHRIKE missile. They provide the electrical and mechanical interface between the SHRIKE guided missile and the launch aircraft.
NOTS developed Shrike, the first successful antiradar missile, beginning in 1958 as a direct response to Fleet needs, and China Lake personnel took the missile to the carriers in Southeast Asia in the 1960s. During the Vietnam War, aircraft launched the first combat firing of the Shrike. Shrike was developed following many of the same principles that guided Sidewinder development: simplicity, reliability, maintainability, producibility, improvability. The AGM-45 was the first mass produced missile built specifically for the anti-radar mission, and more than 20,000 Shrikes were produced beginning in 1962. The Shrike’s effectiveness was limitated by the requirement that the missile be pointed at the intended target radar during launch, and that the Shrike will lose its lock if the radar ceases to radiate. The Shrike is now being replaced by the much improved AGM-88 HARM.

The AN/ALE-40 Counter Measure Dispenser System (CMDS) provides expendable counter measures stores and dispensing for multiple aircraft platforms. The AN/ALE-40 system is a means by which the pilot can release chaff or flare, depending on the threat type, to counter any homing of a missile to the plane. This is a very simple yet effective system. Chaff looks like millions of tiny strands of aluminum foil and each strip is cut to length to match the various wavelengths of the radar. Using chaff to combat radar was used as early as WWII and still proves very effective against nearly all radar threats. Flares are white hot magnesium that are designed to defeat a missile’s infra-red (IR) tracking mechanisms.This system is manufactured by Tracor. Source @fas.org

The state-of-the-art, high performance seeker incorporates an advanced IRCM & background rejection capabilities. The missile includes a highly effective fragmentation warhead. Python 4 is a very nimble “fire and forget” missile with an improved maneuvering capability. It has an advanced homing head with a lateral “squint” capability which allows it to receive signals from the line of vision of the pilot who sees the enemy plane through a special (Elbit-developed) helmet. The missile receives these signals and hits the enemy plane without requiring the pilot to steer his aircraft at the enemy plane. The Python 4 can be launched at a range of over 15 km, its warhead is over 11 kg, and its electromagnetic proximity fuze is one of the best in the world.

F-5T-Tigris glass cockpit
Developed by the Israeli firm RAFAEL, the Python 5 is an air-to-air guided missile which is launched from a fighter aircraft (Kfir, F-15, F-16, Sea Harrier, etc). The Python 5 is powered by a solid propellant rocket engine and is armed with an 11kg, detonation-proximity warhead. Traveling at Mach 4, this precise weapon has an operational range of 22 km. It is equipped with an electro-optical imaging infrared seeker (IIR or ImIR) which scans the target area for hostile aircraft, then locks-on to target in its final phase. The Python 5 is a fifth generation of air-to-air Python missiles. The missile allows the pilot to engage an enemy aircraft with a revolutionary full sphere launch capability. The Python-5 is the most accurate and reliable air-to-air missile in the Israeli Army’s inventory and one of the most advanced guided missile in the world.

Derby BVR Air-to-Air Missile
Derby (Alto) is a beyond visual range (BVR) air-to-air missile (AAM) developed by Israeli defence company Rafael Advanced Defense Systems to meet the combat needs of the armed forces.
The Derby AAM can be integrated onto a variety of fighter aircraft such as F-5, F-16 Fighting Falcon, Gripen E and Mirage and is capable of engaging aerial threats from short ranges and near-beyond visual range.
Derby’s variants include I-Derby and I-Derby ER (Extended Range). The upgraded I-Derby AAR missile is equipped with a software-defined active radar seeker and was unveiled at the Aero India 2015 exhibition held in Bengaluru, India.
The I-Derby ER advanced active radar missile was unveiled at the Paris Air Show 2015. It features a solid-state active radar seeker and a dual pulse rocket motor, which provides an operational range of up to 100km.
The missile can be launched from Sea Harrier jet fighter, F-16 (Block 52) Fighting Falcon, F-5E Tiger II, and IAI Kfir combat aircraft.
The weapon has a length of 362cm, a wing span of 64cm and a diameter of 16cm. It weighs 118kg and is armed with a 23kg warhead. The seeker and guidance system are fitted in the front of the missile, while the rocket motor is placed at the rear.
The missile can operate in lock-on before launch (LOBL) and lock-on after launch (LOAL) modes. In LOAL mode of operation, it receives target information after being deployed from its launch platform, while in LOBL mode, which is enabled in tight dogfights, the seeker is locked onto the target before the missile is launched.
The active radar seeker provides guidance and improved target accuracy at radio frequency (RF). The radar’s look-down / shoot-down capability enables the missile to attack targets below and along the line of the horizon.
Derby’s high-explosive fragmentation (HE-FRAG) warhead defeats non-armoured targets and light material targets.
The weapon features fire-and-forget engagement capability and can be optionally fitted with advanced, programmable electronic counter countermeasures (ECCM) for operation in hostile environments. Data @airforce-technology.com
ELBIT Gets $85 Million Asian Contract to Upgrade F-5 Aircraft
Elbit Systems Ltd. announced today that it was awarded contracts from an Asian country in a total amount of approximately $85 million. Most of the amount is for an F-5 aircraft avionics upgrade program and the balance is for the supply of electro-optic and communications systems.
The name of the country in question was not revealed. Maybe it chose to remain anonymous because it does not want certain other countries to know that it does business with Israel.
It would be really funny if it turned out to be North Korea, but they probably don’t have any of the American made F-5 aircraft.
The contracts will be performed over a three-year period. Elbit has been providing upgrades for the plane including new mission computers, advanced glass cockpits featuring 3-color displays and operational capabilities, as well as the DASH IV Helmet, Weapon Delivery and Navigation Systems, for years.
Produced by Northrop Grumman, the F-5 Tiger is an agile, highly maneuverable, reliable supersonic fighter, combining advanced aerodynamic design, engine performance and low operating costs. Since 1959, more than 2,600 were built by Northrop Grumman and under co-production and licensing agreements with Canada, the Republic of China, the Republic of Korea, Spain and Switzerland. It has also been used by Norway, Brazil and of course the U.S.
Bezhalel (Butzi) Machlis, President and CEO of Elbit Systems commented, “Asia-Pacific is a very important market for Elbit Systems, and we are pleased to be awarded further programs in the region, which programs benefit from the synergies across the various parts of our organization. We are proud to have been selected to perform this aircraft upgrade program, building on our vast know-how and experience in F-5 avionics modernization projects.”
“We have witnessed a growing demand for upgrades of this nature, and we trust that further customers will follow, benefiting from a mature aircraft upgraded with market leading technologies.”
In other Elbit news, the company has said that it expects a drop in its third quarter earnings of $15-$20 million due to the recent depreciation of the Shekel. Posted Wed, Oct 22nd, 2014 by @jewishbusinessnews.com

It seems the Royal Thai Air Force upgrades past and present of the F-5s have been kept confidential there is very little info and it is notable that some F-5s have 1 canon which may suggest some were fitted with FIAR Grifo F/X Plus multimode radar. Elbit have also kept all upgrades confidential.
Single-seat fighter prototype. Only three aircraft were built.
The three prototypes were given the U.S. Air Force designation YF-5A.

The temporary designation given to the Northrop F-20 Tigershark, armed with General Electric AN/APG-67 radar.
Damn the F-20 is HOT! But back than it came out at the same time as the F-16 which was hotter! But looking at it now I wish they built it!
In comparison to later fighters, the improved F-5E had some weaknesses; these included marginal acceleration, rearward visibility, and fuel fraction, and a lack of Beyond Visual Range (BVR) weapons once such radar guided missiles became reliable during the 1980s. The F-5G, later renamed the F-20 Tigershark, aimed to correct these weaknesses while maintaining a small size and low cost to produce a competitive fighter. Compared to the F-5E, it had 60% more power, a higher climb rate and acceleration, better cockpit visibility, more modern radar and BVR capability, and competitive performance with fourth generation fighters.
General Electric AN/APG-67 radar
Like the F-5, it had better cost effectiveness as it had the minimum necessary features relative to its competition to perform its air superiority mission. As an example, in the 1960s and early 1970s, the F-5’s lack of BVR missiles was not a significant disadvantage as the kill rate of such missiles was approximately 8% to 10%, and the performance and loss of surprise (radar warning to the enemy) cost of carrying them was not practically justified. By the early 1980s, the American AIM-7 Sparrow radar-guided missile in its “M” version was realistically exceeding a 60% kill rate, and was integrated onto the F-20.
Brigadier General Chuck Yeager, test pilot and the first man to break the sound barrier, referred to the F-20 as “the finest fighter”. Despite its performance and cost effectiveness, the F-20 lost out for foreign sales against the similarly capable, more expensive F-16, which was being procured in large numbers by the U.S. Air Force and was viewed as having greater support.
