The YF-7 Sylphide was the first mass-produced Veritech fighter primarily used by the Robotech Defense Force. Several models and upgrades were developed throughout the First Robotech War and Malcontent Uprising.
After the failure due to lack of deployment machine number of the reason the increase of the initial acquisition costs associated with the excess of development costs of the VF-4 project to deliver an advanced, capable and affordable veritech fighter to replace the obsolete VF-1 Valkyrie, two lighter veritech design projects were started, with the intention that the winner would be chosen as the UEDF-wide general-use Light-Weight Medium Variable (transformable) Fighter project named after Advanced Valkylie project, (A.D.V.) .
The two designs became the VF-6 Alpha (Legioss, VF-X-6 Genia
cancelled ) and the VF-7 Sylphid (NAVY variant feminine noun "sylpheed" ).
However, while the expeditionary forces elected to produce the VF-6 Alpha in large numbers, the Earth-bound Tactical Air Force disagreed with the choice of this design. Specifically, the TAF cited the VF-6 Alpha's lack of hardpoints and resulting loss of the ability to mount heavier ground attack missiles, and it's general reliance on short range missiles (implying other mecha with longer ranged missiles were also required). Finally a longer battle-turnaround time for the VF-6 Alpha was expected due to the use of an ammunition-fed gun pod and numerous internal missile holders where the Sylphid had only four hardpoints to load with new missile containers. In the end, the TAF decided to acquire the VF-7 Sylphid for its forces rather than the VF-6 Alpha. Sylphid Cockpit The Sylphid shows distinct VF-1 influences in its forward hull, and the combined engine block/arm sections were reminescent of the failed VF-4. Compared to its predecessor, the famous VF-1, the VF-7 can carry its missile armament with it through all speed regimes, unlike the elder plane, whose missiles would be torn off their mounts long before it reached its maximum speed. Additionally, the Sylphid no longer carried a gun pod, or even ammunition dependent weapons. On the debit side, the Sylphid can only fire its missiles in Fighter mode or in certain flight regimes in Guardian mode, when the engines are pointing aft.
The Sylphid entered service with the Tactical Air Force in 2021, and remained in service with this unit until the Invid invasion. It became the primary tactical airborne veritech mecha of the Southern Cross' Tactical Air Force. Over the years the electronics were regularly updated, and in 2026 a new version with two more cannons and more powerful engines replaced the earlier one on the production lines, with older models being refitted to the new standard within two years. The two variants can be distinguished by the cannons on the arms and the fact that the FF-3001 fit had three sub-nozzles per engine, and the FF-3031 had four. Slated for replacement in 2034, the Second Robotech War interfered with the development of the X-34 project, the Sylphid's intended successor design. Development was stopped during the war both to concentrate on the rapid production of the existing veritech, and to later evaluate all combat lessons learned and incorporate them into the new design. However, the Invid Invasion in 2031 ended this project in its infancy.
This plane was shown to be less than successful against the Robotech Masters, partly because its bases kept getting shot up, but mainly because as a fighter it was completely overclassed by the Assault Carrier, against which it could not mount heavy enough weapons to be fully effective. Against the Invid, the remaining Sylphid were moderately effective during the initial invasion, but soon all support bases had been destroyed and keeping the remaining Sylphids active proved to be almost impossible.

The armor of the Sylphid is composed of an advanced titanium-steel alloy. The armor stops all small arms fire, provides excellent protection against heavier infantry weapons, such as a 12.7mm machinegun round, and good resistance to light mecha-mounted weaponry, such as the Zentraedi 22.3mm HE autocannon round. The resistance against heavier weapons is markedly reduced, however.
The Sylphid provides full protection from nuclear, biological, and chemical hazards, using an overpressure cockpit environment activated by radiation and hazardous chemical sensors, or manually when biological warfare conditions are anticipated. The internal consumables supplies can provide atmosphere for one day maximum.
A,B,C,D variants Edit
- VF-7A, -B: Served with the Southern Cross' Tactical Air Force from 2021 until 2027.
- VF-7C, -D: Began to replace the VF-7A, -B in 2025 and served until the Invid invasion.
The Sylphid entered service with the Tactical Air Force in 2021, and remained in service with this unit until the Invid invasion. It became the primary land based tactical airborne veritech aircrafts of the Southern Cross' Tactical Air Force.
Over the years the electronics were regularly updated, and in 2026 a new version (C,D) with two more cannons and more powerful engines replaced the earlier ones on the production lines, with older (A,B) models being refitted to the new standard within two years. The two variants can be distinguished by the cannons on the arms and the fact that the FF-3001 fit had three sub-nozzles per engine, and the FF-3031 had four.
N and ND variants Edit
The place of the conventional reference materials is a derived type that has been described only that there is a fuselage of dual tires (Double), it is becoming clear that in fact is a carrier-based "variable fighter" type to be operated in vessels .
Initially, but was a shorthand nickname of feminine noun "Sylph" (feminine noun "sylpheed" as naval usage) designed by divisible to complete land base operation of the Air Force , primary VF-1 Valkyrie, the VF-4 Lightning pre-designed as a carrier-based fighter. The it is because had Just not manifested (or building material), the appearance of such specially designed aircraft, required the development of a new fighter aircraft originally.
VFA-6 Alpha (Legioss) United Earth Expeditionary Fleet Forces (UEEF), The areas of the wings loading is strangely on that small too high, tail grounded at a slight angle of attack despite requires a high angle of attack on the aircraft carrier clothes ship, the worst three-point grounding is not possible of and selection of the delta wing type, always-on and strangely short ProtoCulture resources) replacement interval by the severity of the energy consumption of the gravity control device (although auxiliary applications), atmospheric performance is lower than the VF-4 Lightning for, is impossible to break the design itself, is a newer design is still better, are excluded in order to not meet the Navy's requirements of carrier-based fighter, In any case, there is also a face of the Navy for the expedition fleet Force adopted The intent of was not.
On the other hand the time and budget to new development (60% of maritime aircraft carrier is lost in the previous war, mother ship reconstruction in the priority is not empty hand to equipped aircraft development) in even cry, VF-7D, non transformable easy production variant F-207D (both double the seat type) was the mother, VF-7N, F-207N, and that there was revised design.
These must be Prometheus class-No.5 ship CVS-105 "Ceres" and four other total 120 aircraft and replacement spare 20 aircraft in order to be mounted on ships, carrying the modified design, Northrop-Grumman cooperation destination of Northrop Grumman alone is a shortage, and that he looked up the cooperation to the retired designer of deep Vought or L.T.V. Aircraft Industries of experience in career based aircraft design.
This modified design history is a long period of time until the commissioned the Dassault Rafale M type of Avions Marcel Dassault-Breguet Aviation (AMD-BA) company is put to the French Navy,F-8E(FN) Crusader who played as inter-operable carrier-based fighter in the Clemenceau-class aircraft carrier (FN): It traced the history similar to modify or commissioned history of the Crusader.
From the fact that advanced technology is required to landing of the ship boarding aircraft, double seat type have been developed prior to the singled seat type of aircraft carrier air wing commissioned a year ago ｔandem dual seats type of crew conversion training they went to the mission.
From the fact that from the other hand the beginning it has not been designed as a carrier-based VERITECH fighter, a failure occurs in the transformation system by the impact of the landing on the flight deck to a Career, applying a hard time maintenance personnel, machine with the chief of the maintenance particular, responsible for the maintenance responsibility of transformation system it was decided.
