Introduction of the VA SeriesIt was pointed out that the general-purpose FCS weapon control system installed in the general purpose VF series, which had been developed to be able to fight in all regimes, was not useable for specialty attack weapons, and the lack of a bombload was a deficiency (of the VF series) for regional attack missions. Moreover, the high production costs from the use of an increased number of processes and new materials (in the VF series) became a problem, too.
Though, this problem did not come to light while combatting against Bodolza, because the main duty of the VF series was air defense duty in space, since the start of the Megaroad (Emigrant Fleets) and emigration has started, and with the point of regional control [supression, supremacy], the very bad cost-performance of the Valkyrie has been clarified.
Starting at this time, airframe development harvesting the idea of specialized fighters, and a lot of airframes excelling in a specific-use were developed. It can be said that (VFs developed) after the VF-1, such as the VF-4, VF-5, VF-5000 and so on, are specialized fighters of that idea. Originally, even though the Destroids undertook regional attacks, the VA series has been developed to answer the development ability of a deployable attack craft.
Before the development of the VA series, the VF series undertook the control [supression, supremecy] of a region's ground and skies by maintaining authority by air-superiority; and though the VF series did attack positions [locations, bases], because of it's weakness of offensive power, there are plenty of demonstrations of the VF series (limited) ground control effectiveness, as it had to do it in a large quantity of spread out waves. Then, a variable attack craft, with a ground-attack use [only] FCS installed, and having the ability to be equipped with a large amount of armaments, was developed.
VA-3 Invader (partially con't on page 73)
The VA-3 is an all-regime attack craft, developed as a specialized craft for limited area [local] attacks with strategic reaction warhead attacks and conventional bombs. With abundant know-how in ship-board attack craft, the Grumman [Guraman] Aircraft Department of the Northrum [Noosuromu] Company, took charge of development (of the VA-3).
It is designed for the Lo-Lo-Lo attack* ideology, that keeps (the craft) flying at low altitude from takeoff, to the attack and return; without consideration of the velocity, performance and so on, but valuing a durable, high-survivability airframe design. From the beginning, it's mobility at low and high altitude in the atmosphere, due to it's slightly rearward angled main wings and rounded nose-line, is valued. A large nacelle exists in the middle of the main wing, which becomes the arm in battroid form. Though the VA-3 is not equipped with an afterburner, as it is thought that it will mainly be used for low-level flight in an atmosphere, supersonic flight is possible because there is surplus engine thrust.
The battroid mode has the peculiar shape of craft in the Zentraadi line. Moreover, because it's defensive ability for ground combat is stressed more than it's ability as an aircraft, the VA-3's airframe can be said to be characteristic of a Destroid.
The VA-3 automatically navigates, as well as has an FCS that automatically takes aim after target acquisition with the radar. This is with an inertial navigator as the system center of the computer, where data from the Doppler device is processed, and attacks (are formulated) because of radar searches against the target; and it is said that the VA-3 is equipped with electronic equipment that can do all of this completely automatically until (the VA-3) withdrawals.
To improve the attack accuracy on the target, a TRAM** standard device, that combines infrared rays and laser detection data with the radar system, is developed at the same time. The VA-3 doesn't have any fixed armaments, however it has 6 hard points on the main wings, and 5 hard points on the body [trunk], and boasts a total payload amount of up to 19,820 Kg.
The VA-3B is equipped with a forward-looking [observance, surveillance] infared sensor and a low-altitude flight camera in the lower side of the nose. It is a model that has changed the electronic equipment system and has improved all-weather performance.
Pg 73captions:1. Head detail in battroid mode. There are four accessory cameras surrounding the main camera in the center, and (with them) the ground monitoring and surveillance capability has been improved. This aircraft has the cockpit in the head, which is unusual in a variable aircraft.
2. In the volumous loading of the large VA-3, a large gattling gun pod for ground suppression is often carried. In a design that unites the flow of a Zentraadi Battle Pod, (the Zentraadi lineage) can especially be seen in the arm manipulator.
3. VA-3 Battroid Mode
Electronic Warfare FighterA derived type, made into a specialized electronic warfare airplane, called the EVA-3A.
It's main duty is to disrupting the enemy radar and do reconnaissance before an attack, as well as providing guidance [leadership] to the Attack Fighters.
In this airframe, the offensive equipment of the VA-3 attack craft has been removed, and in the (already) installed type of electronic equipment, the navigation equipment has been strengthened, the nose has been lengthened into a two-seater for the boarding of a special operator who handles the electronic equipment in the EVA-3A.
The body [trunk] of the craft and the vertical tail have been redesigned; with the ALQ-200 Multi-Band Track Breaker*** that can deceive enemy radar, the ALQ-192 Communication Jamming Device, and the ALQ-199 Tactical Noise Jamming Device installed there.
Besides this, it is possible to carry frequency band pods suited for a (specific) function [duty, task] on the hardpoints; up to 5 of these pods can be suspended.
The EVA-3, as the eyes of the mobile attack force, are deployed as one company [battery, troop] of 4 craft per attack air group.
* Lo-Lo-Lo Attack: "Ingress, Attack, and Degress at low Altitude"
** TRAM: Target Recognition and Attack-Multisensor
*** Track Breaker: are usually employed against tracking radars in single target track mode, these are typically fire control radars associated with SAMs, AAMs and AAA. Track breaking techniques are therefore of major importance in tactical and strategic aircraft.
Track breakers attack the automatic tracking mechanism of the victim radar. If the threat is a pulsed radar a track breaker will usually transmit a 'cover pulse' at the same time as the return pulse. This masks the return and the victim tracking mechanism is then allowed to lock on to the cover pulse rather than the weaker real return. The jammer has then seduced the tracking mechanism and can, within limits, move the target about its real position and typically turn it off to break lock.
The target will often be made to erratically jitter which makes it impossible to accurately guide a missile or fire a gun at the target. (from
