The AC-88 Taipan is an air-superiority fighter developed by Inyursta for the Inyurstan Air Force, and later Inyurstan Navy. It is named after the Taipan, a genus of highly venomous and formidable snakes.

As a dedicated air-superiority fighter that has seen widespread service, it is both one of the most famous and one of the most feared aircraft in the Inyurstan arsenal.

Development

The Taipan program began as an indigenous effort to develop a 4th-Generation "pure" air-superiority fighter along the same lines as the original F-15. Designers and engineers also borrowed the same phrase "not a pound for air-to-ground" when describing the duties and expected roles of the Taipan. In December of 1996, the original X-88 prototype made its maiden flight, performing several sonic booms, Herbst Maneuvers and Pugachev's Cobra. It was soon after ordered into production and adopted by the Inyurstan Air Force.

However, even after the Taipan entered service, the program continued development. Part of this was due to limited access to forthcoming technologies (AESA radar, IRST, etc.), and in part due to air-to-air lessons learned in the trial-by-fire crucible that was the Lolloh-Ruol Wars. Incorporation of these upgrades, while long-coming, was made easier by the initial designers leaving "empty space" both physically and in terms of software code, with the intent of adding plug-and-play additions in the future.

Design

Main design features of the Taipan include swept wings, a single vertical tail, and the presence of forward canards and a Leading Edge Extension (LERX). Swept wings allow the AC-88 greater wing loading, stable center of lift, and a smoother transition between subsonic and supersonic speeds. To compensate for the increased drag caused by the swept-wings, a single all-movable tail is situated between the two engines, giving it less drag during straight-forward supersonic flight than would two vertical tail. At high angles of attack, both the canards and LERX are used to reduce the effect of the fuselage "blocking" the tail fin and keep airflow over the tail.

Later models also feature a forward air brake and thrust-vectoring engines; all features which give it super-maneuverable capabilities.

Power

Early AC-88 used CP-1990 conventional turbofan jet engines. However, because these engines were produced at the infancy of the Inyurstan arms industry development, with little external support or input, they were not optimized to make the most of available technologies or thrust output. This is not to say that the engines were ineffective, but later on IEK would secure the sale of Nifonese Kojima K50 variable-cycle engines for the Block II line which would power the Taipan with over 170kn wet thrust (112kn dry), giving it supercruise capability, among other enhancements to its aerial maneuverability. The K-50 engines also allowed for increased kW generation, which allowed the Block II+ models to support their more diversified array of avionics.

Avionics

3D Design of the AC-88

Original models carried the ESQ/AS-1 Razor radar, an infant project giving the Taipan a radar range of roughly 100km against 3m² targets and without IRST systems; however both features would later be improved upon with future models. The Block II upgrades featured significant improvements; including new radar, radar-warning receiver (RWR), IRST systems, helmet-mounted-display, and additional RWR/MLD antennae & nodes.

For its primary radar, Block II+ models of the AC-88 use the ESQ/AS-7 Yaraca, an impressive solid-state AESA X-Band radar. The ESQ/AS-7 is capable of tracking up to six individual 1m² targets at ranges of up to 200-400km, depending on beam width. The nose-mounted ESQ/AS-7 can rotate approximately +/- 25^o, when paired with the wide-band capabilities this can allow the Taipan to track targets at angles approaching perpendicular. A secondary pair of lightweight ESQ/AS-A-8 L-band AESA radars are also installed bellow the LERX allowing for enhanced detection of stealth targets and redundancy during high-EW situations.

Infrared tracking & targeting capabilities are provided by the CAT EYE I passive IRST, which are linked to the pilot's HMSD. The main node is located under the nose, while additional censors are installed one under the fuselage and two on either side of the tail facing up and backwards. Additional nodes are also fed into the plane's targeting software, allowing for tracking and engagement of highly maneuverable aerial targets (especially those performing post-stall maneuvers) even when they have escaped into the pilot's blind spots.

Current models of the AC-88 are equipped with the LIDACS-II Counter-Measure Suite, a multitool of counter-measure options including chaff, flares, two IR Jamming/dazzler nodes and ECM/DRFM jamming. This system is synchronized with the Taipan's ESQ/CE-11 radar warning receiver (RWR)/missile launch detector (MLD); a system of 16 (Block I) - 28 (Block II) antennae streamlined through the body and three infrared sensors (no display) filling the gaps in coverage left by the CAT EYE system. It can also aid in detection of enemy aircraft (such as AWE&CS or powerful fighter radars) when the Taipan is being "painted" with radar beams.

History

The Lolloh-Ruol Wars became the first conflict for the Taipan's to see combat. They proved quite successful at surviving onslaughts of both Cold War-era relic fighters and modern 4.5 and 5th-gen aircraft in both medium-range ("short BVR") and short-range engagements.

Due to the lessons learned in the Lolloh-Ruol Wars, designers and military strategists began scheming with the idea of using the Taipan as an interceptor to destroy bombers and C4ISTAR assets. Tests were done with the American AIM-54 Pheonix integrated onto the AC-88, and such load outs saw limited use in combat; however, they would later pave the way for the integration of the C-300 Scapèle onto the aircraft.

In the Greco-Bulgarian War they were deployed but to limited use and effect due to the relative lack of hostile air targets.

The AC-88E Taipan Block II made its debut and served as the backbone of Inyurstan support during the DEN Invasion of Colombia.

AC-88E Taipan's were responsible for the interception of two Hayesalian CBU-160 Super Blackjack bombers during the San Meresque Incident.

Maneuvers

Aerial Scorpion

The "Aerial Scorpion" is a multi-plane (requiring 3-6 fighters) maneuver for BVR against an approaching enemy.

Fire Flower

The "Fire Flower" is a last-ditch WVR maneuver that was first observed during the Air Battle of Dekkar. It is performed by a single, outnumbered fighter against multiple enemies within visual range.
