The McDonnell-Douglas F-203 Dragon II was a multi-role fighter designed shortly after the crash of the SDF-1 by the United States and Sweden, utilizing many of the new technological advancements from the downed alien spaceship. It was later accepted into service by the UN Spacy and served as their primary conventional fighter through the First Robotech War.

Development

Background and Design

Design of the F-203 Dragon II began in early 2001, soon after the crash of the SDF-1, by a joint effort between the United States’ McDonnell-Douglas and Sweden’s Saab Scania company. Because both the F-15 Eagle and other existing fighter designs were getting rather old for the air supremacy role, and the F-15’s newly completed successor, the F-21 Talon, was costly to produce in both money and time while still utilizing pre-SDF technology, The United Nations Space Agency (UN Spacy) initiated a Joint Strike Fighter competition to provide a new fighter for the Unified Forces. McDonnell-Douglas/Saab Scania won the competition with the YF-23 Dragon II. The Dragon’s role was to eventually replace the Talon and the venerable F-14 Tomcat in the air supremacy role.

The F-203 Dragon II was named in honor of the Saab 35 Draken, which was the Swedish word for Dragon. Indeed, in the Swedish Air Force, the F-203 served as the Saab 39 Draken II.

Since the Dragon was intended for fast production (indeed, it went from design concept to production in an unheard of two years!), as many of-the-shelf components and technologies were used as possible. The front of the Dragon is therefore a marginally smaller version of the F-15 cockpit, and the engines are improved versions of those on the Talon that utilized new materials discovered after the crash of the SDF-1. The exhausts were vectored-thrust nozzles. In addition, the US Marine Corps specified the incorporation of V/STOL capability to allow it to fly from short deck aircraft carriers. The original electronics suite also utilized standard components, but these were quickly replaced in follow on versions with newly developed systems.

The wings were unique to the Dragon, and incorporated the newest in aero dynamical science when first designed. The armament fit was a new 16mm rotary cannon in each wing root with a large number of small conformal pylons as pioneered on the F-16XL for external loads. However, it soon turned out that the new lower-caliber cannons were less effective than was hoped, in addition to being mechanically unreliable. The manufacturers’ solution of mounting a redundant pair was less than ideal, and the guns were soon replaced by Swiss KCN single barrel 25mm cannons.

The F-203A, B and C versions were mass produced by the United States and Sweden, and saw much use in combat during the Unification War. (The Dragon was accepted into service by the United States as the F-23, while the UN Spacy gave the fighter the designation F-203. To avoid confusion, the Dragon II will be referred to as the F-203 from here on.) In 2006 an updated version, incorporating many of the Tirolian technologies that went into the VF-1 Valkyrie, was put into production as the F-203G, H and J (in the US Air Force, Navy and Marine Corps). The improvements involved the installation of a far more powerful radar/EW suite, with the new Hughes AWG-20 radar system, active missile jammers, and so forth. This suite became standard equipment for most advanced fighters throughout the UN Spacy, being used on craft ranging from the F-14S to the VF-1.

The Dragon saw some service in the Zentraedi Uprisings, but being a conventional (chemically propelled) fighter, it could not sustain high Mach speeds the way the Zentraedi Fighter Pods could, and it was far inferior to the Quaedluun-Rau Power Armor at the sub-Mach speeds which the Zentraedi mecha could reach. It was therefore quickly replaced in the UN Spacy inventory by VF-1 Valkyrie Veritechs. A number of F-203s saw service in the hands of the Royal Navy (United Kingdom) and the Spanish Armada for use on ski-jump equipped carriers, and with various European Union Air Forces.

Engines

The F-203A to F models were equipped with two Volvo Aero RM18 turbojets. The RM18 was a derivative of the General Electric F414 chemical turbofan. The RM18 was interesting in that it deleted the bypass section of the F414 turbofan, thus turning the engine into a true turbojet. Though this made for an engine that was less efficient at low speeds, the design made up for it with increased thrust, lower weight and more compact dimensions. These power-plants produced 98 kN of afterburning thrust each, and allowed for super cruise at speeds above Mach 1 without the use of afterburners. For the F-203 G through M models had the improved RM19 with 102 kN of afterburning thrust. On the final F-203N/P, the improved General Electric F424 with 110kN thrust was used instead, Volvo Aero having ceased to exist. All models were equipped with vectoring nozzles and the C, F, J, M, N and P variants had ducted fans powered by the main engines which gave the fighter V/STOL capability.

Armament

Early F-203s (A to F) had two M-65 16mm six-barrel, hydraulically driven rotary auto-cannons with linkless feed, mounted in left and right wing roots. The M-65 fired light explosive armor piercing (LEAP) ammunition and hypervelocity tungsten AP flechettes at 6,500 rounds per minute, with a max effective range of 1,200 meters. Ammunition payload was 1500 rounds total. These cannons were failures and were replaced on all Dragons by 2011 with twin Oerlikon KCN 25mm autocannons, firing APHE (Armor Piercing High Explosive) or HEI-T (High Explosive Incendiary – Tracer) rounds at a maximum rate of fire of 2000 rounds/minute. The ammunition supply was 275 rounds/gun.

All F-203s had twelve hard-points for ordnance, 5 under each wing and 2 on the centerline. Typical air-superiority load (for the N variant) was 8 medium range (65 km) Mach 3.0 combined active radar and thermal imager guided AMM-1 Stiletto missiles, four under each wing, and a large conformal fuel tanks occupying the two centerline hard-points.

Operational history

The F-203 was the most prolific conventional fighter of the First Robotech War. In addition to serving with the United States Military and UN Spacy, the F-203 was purchased by virtually every Air Force and Navy in the Western World. Its versatility allowed it to operate in all environments, from fixed airfields to ski-jump equipped aircraft carriers. The F-203 served as a front line fighter for the United Earth government until 2020, and with many third world countries until the Invid Invasion.
