The '''Gruening F7M ''Wedgetail''''' is a [[Meridon|Meridonian]] carrier-capable, supersonic, twin engine, single seat, twin tail, stealth {{wpl|fighter aircraft|jet fighter}}. Envisioned to supplement and replace older models of aircraft in service with the [[Meridon Defense Forces]] and increase commonality, the project is unique in that it is the first joint venture of a fighter aircraft from the initiation of the project to include both Air Forces and Navy design inputs since the 1960s- prior, Air Force fighter designs had fallen through, resulting to the utilization of Navy designs, as was the case for the [[Gruening F5M Lynx|F5M Lynx]] and the {{wpl|Boeing F/A-18E/F Super Hornet|F6M Wasp}} programs.

The Wedgetail was designed from its inception to be a multi-role oriented stealth fighter capable of most combat missionsets required of fighter aircraft, including air superiority, ground attack, close air support, electronics warfare,maritime strike, reconnaissance, interdiction, and the employment of standoff weaponry. The Wedgetail is also unique in that it is one of the few aircraft globally that features compatibility for both 'probe and drogue' and boom- method refueling, owing to differing operational requirements from the Air Forces and Navy.

The Wedgetail is also unique in that it is one of the few aircraft globally that features compatibility for both 'probe and drogue' and boom- method refueling, owing to differing operational requirements from the Air Forces and Navy.
 
Originally designed for the Meridonian Navy to supplement and eventually replace the {{wpl|McDonnell Douglas F-4 Phantom II|F4M Spectre}} in an air superiority fighter and interceptor role, it has been significantly developed and upgraded since its initial introduction to compose a major part of the tactical aircraft of both the Navy and the [[Meridonian Air Forces|Air Forces]], where it has been made capable of multirole missions.
 
Originally designed and optimized for long-range air to air interception  of cruise missiles, bombers, and fighter aircraft, a need for long-range strike capabilities on naval aircraft became apparent, which saw later variants upgraded to become capable of precision bombing and reconnaissance via the Tactical Aircraft Navigation and Designation Module (TANDEM) pod. Following the collapse of the Air Force's Air Supremacy Initiative in the 1980s, the F5M was introduced as an interim solution to fill a gap in the air superiority field. Collaboration with the Navy and Air Forces in the 90s saw the introduction of the "Super Lynx", an enhanced design featuring leading edge extensions, integrated targeting and navigation systems, enhanced avionics and airframe construction, and a substantial enhancement in its mission profile with the ability to launch standoff air-to-ground munitions.
 
Currently, it serves as one of the mainline fighter aircraft of both services alongside the {{wpl|Boeing F/A-18E/F Super Hornet|F6M2 Wasp}}, where it remains ideally suited for air combat missions. Built around the {{wpl|AIM-54 Phoenix|MUA-55 Phoenix}} long-range air-to-air missile as its primary armament, it remains one of the most potent long-range interceptors in service, though it has been upgraded to be able to field the {{wpl|AIM-120 AMRAAM|MUA-120 CAIMS}} alongside the Wasp.


Marketed as a 5.5 generation fighter, the aircraft's software and airframe are designed with modular architecture to be capable of future upgrades, as this aircraft is planned to serve for the majority of the 21st century and will serve alongside the [[Gruening F9M Osprey]], a variant developed from the Wedgetail's own parts and design.


The Wedgetail is currently being introduced to flying squadrons in the Air Forces and Navy where it is replacing F5M airframes.

The F5M was designed based both on experience flying the F4M Spectre as a naval fighter, and on perceived needs of the carrier air wing in conducting force projection and self-defense operations. Seeing the threat of missile-armed bomber flights as an emerging threat towards the carrier group, the F5M was designed with long range and an air-to-air focus in mind while ground attack missions would be relegated to the F4, a role in which it had proved itself more than capable of performing. Like the F4M, the F5M was designed around a two-crew design with a pilot and radar intercept officer deemed better able to manage air intercepts.
 
A number of emerging technologies were included in its design, chief among those its variable geometry wings, which move forward for slower flight and move rearward for faster supersonic flight. It included a number of innovative control surfaces to improve its low-speed handling, which was necessary for carrier operations. Originally it was powered by a pair Altern MG-410 afterburning turbofan engines, which proved to be prone to compressor stall incidents at high angles of attack, and was later replaced by Hollon FT80 engines, which provided a substantial increase in both reliability and performance. Both engines are supplied with rectangular intakes equipped with movable ramps, bleed doors and other such functions. Landing gear is provided in a tricycle arrangement, and is reinforced for carrier landings.
 
The Lynx's weapons system was based around the utilization of the TAI-81 X band pulse-doppler radar, the first in use capable of launching using {{wpl|track while scan}}; and the {{wpl|AIM-54 Phoenix|MUA-55 Phoenix}} missile, a very long range air to air missile intended for intercepting targets at ranges in excess of 100 nautical miles. Utilizing the Phoenix for long-range intercepts and the {{wpl|AIM-7 Sparrow|MUA-7 Falcon}} for escort and air intercept missions. From the outset it was armed with the {{wpl|M61 Vulcan|Mark 40 20mm cannon}} in a nose mount with 600 rounds of ammunition. The Lynx carries a radar warning receiver, chaff, flare, and models from the F5M4 and later are integrated with electronics countermeasures systems to defend against incoming missiles.
 
The Lynx featured pioneering developments in pilot interface in Meridonian fighter craft, including the first multi-function HUD, hands-on throttle and stick (HOTAS), and early multifunction displays, features which would prove instrumental in the design of later combat aircraft.
[[File:F5m_cockpit.png|thumb|right|550px|Pilot cockpit layouts of the F5M2 (left), F5M5 (center) and F5M7 (right).]]
Lynx models from the F5M6 and later improve vastly upon the original design of the base model F5Ms (F5M through F5M5). The F5M6 introduced leading-edge extensions (LEX) to the wing root, enhanced visibility cockpit glass, full multifunction glass flight displays, integrated NAV/attack FLIR pods, and HMD integration, as well as allowing for the carrying of standoff weaponry including cruise, anti-satellite, and anti-ship missiles. The so-called "Super Lynx" upgrade vastly improved performance in nearly all aspects over the airframe. F5M7 upgrades, first fielded by the Air Force, feature a full glass display replacing all 'steam gauge' instruments.

==Variants==
==Variants==
;F5M
;F7M
:Initial operational variant, first supplied to the Meridonian Navy in 1974. As initially supplied, it was almost purely an interceptor and air superiority aircraft, with marginal ground strike capability added through unguided bombs and rockets only. It was powered by Altern MG-410 afterburning turbofans, which proved unreliable and prone to compressor stalls especially at high AOAs. All F5M models were upgraded to F5M2 standard by 1983.
:Initial operational variant, first fielded 2023. Air Force variants are designated F7M A and feature a weaker tailhook and lighter wheel mechanism and lack folding wings; naval variants are designated F7M C and feature reinforced landing and arresting gear and feature folding wingtips.  
 
;F7M K
 
:A designated variant of F7M A units in [[Kozakuran Armed Forces|Kozakuran Air Forces]] service. After [[Kozakura]] received partially completed F7M units from [[Meridon]], the Kozakuran National Defence Directorate contracted in [[Morgenroete (Esvanovia)|Morgenroete Aerospace Systems]] to bring the units further in line with Kozakuran defence requirements. This resulted in 40% of the aircraft's systems replaced or modified. Morgenroete also installed a new computing hardware capable of running {{wp|Artificial Intelligence|Heuristic Controllers}} as part of the Kozakuran Armed Forces' ''Networked Sentinel'' military automation program.
;F5M2
;A9M2 Strike Wedgetail
:Upgraded variant of the initial F5M2 variant addressing numerous concerns by the Navy and adding operational requirements for use by the Air Force. Wing vanes mounted in the glove box were permanently removed, and the addition of a second CRT display for navigation was included. Integration with civilian navigational sources including VOR and ILS were integrated for use, including a HUD approach mode. Automatic Carrier Landing System (ACLS) capability was added to this model. A total of 103 F5Ms were upgraded, and an additional 242 were produced to F5M2 standard.
:A lengthened modification of the F7M-A featuring a two-man cockpit, conformal fuel tanks, lengthened wings, and enlarged internal weapons bays and fuselage. It is intended to replace the A8M Gharial in interdiction roles.
 
;F5M3
:Upgrade program conducted in the mid-late 1980s, its primary improvement was replacing the unreliable Altern MG-410 engines with Hollon FT80s, which themselves were a product of the failed Air Supremacy Initiative. Performance increases were substantial, allowing even a fully-loaded fighter to take off without the use of afterburner, a feat unmatched by any other model of naval fighter before or since. Integration was added for the TANDEM NAVLFIR system, including the employment of laser-guided bombs.
 
;F5M4
:The F5M4 was an enhancement project designed to cover perceived gaps in employment capabilities. It was equipped with an enhanced TA-902E radar which mitigated the previous TAI-81's shortfalls to clutter detection, processing speed, and jamming capabilities, and included integration of an air-to-ground radar. New cockpit displays, including the first multifunction displays and an enhanced heads-up display, were added. The F5M4 was also integrated with an inbuilt ECM jammer and provided for the employment of GPS-guided bombs utilizing the TANDEM II pod. Deliveries began in 1992 and concluded in 1999.
 
;F5M5
: Primarily an enhancement program to upgrade F5M2 and F5M3 models to current standards in the mid 90s to early 2000s, the F5M5 label was also issued to upgraded F5M4s, to which the modifications were primarily software-related. The F5M5 included integration of a host of new weapons systems, including the MUA-120 CAIMS, MUB-65, and CUS-154 SOGW.
 
;F5M6
:The F5M6, or "Super Lynx", was a comprehensive re-drawing and enhancement program of the base airframe first produced in 1998. The F5M6 introduced a wide range of new upgrades to the airframe design. Equipped with the enhanced Hollon FT80E engines that provided additional fuel efficiency over the base model FT80s, the F5M6's efficiency and handling was also increased by redesigned leading edges, as well as leading edge extensions and new control surfaces. The F5M6 integrated a fly-by-wire system, a further enhanced TA-910 radar, integrated NAV/attack FLIR, full multifunctional displays for both pilot and RIO, redesigned cockpit glass, integration for helmet-mounted cuing systems, integration of stand off weaponry including anti-shipping, cruise missile and anti-satellite weaponry. Deliveries began in 1999 to the Navy and the Air Force in 2000, and deliveries were completed in 2014.  
 
;F5M7
First fielded by the Air Force in 2020, the F5M7 is a modernization program that saw further flight control enhancements, including a full-panel multifunctional display for the pilot and RIO, as well as the redesign of some airframe components to decrease weight, increase performance, or increase longevity. The Navy received its first batch of upgraded F5M7 models in 2021.

The Gruening F7M Wedgetail is a Meridonian carrier-capable, supersonic, twin engine, single seat, twin tail, stealth jet fighter. Envisioned to supplement and replace older models of aircraft in service with the Meridon Defense Forces and increase commonality, the project is unique in that it is the first joint venture of a fighter aircraft from the initiation of the project to include both Air Forces and Navy design inputs since the 1960s- prior, Air Force fighter designs had fallen through, resulting to the utilization of Navy designs, as was the case for the F5M Lynx and the F6M Wasp programs.

The Wedgetail was designed from its inception to be a multi-role oriented stealth fighter capable of most combat mission sets required of fighter aircraft, including air superiority, ground attack, close air support, electronics warfare, maritime strike, reconnaissance, interdiction, and the employment of standoff weaponry. The Wedgetail is also unique in that it is one of the few aircraft globally that features compatibility for both 'probe and drogue' and boom- method refueling, owing to differing operational requirements from the Air Forces and Navy.

Marketed as a 5.5 generation fighter, the aircraft's software and airframe are designed with modular architecture to be capable of future upgrades, as this aircraft is planned to serve for the majority of the 21st century and will serve alongside the Gruening F9M Osprey, a variant developed from the Wedgetail's own parts and design.
