T390 Tank Family

The T390 tanks are a series of 3rd Generation main battle tanks deployed by the Armoured Corps of the EUF Military.

## Description

They are powerful AFVs that are slowly replacing the aging 1st and 2nd Gen tanks that were slowly becoming ineffective against their adversaries. Unlike its previous predecessors, the T390 series features a ballistic supernova cannon instead of the energy based antimatter bolt cannons previous tanks had, and it was way more effective at destroying enemy vehicles. The T390s also are a step up from their predecessors, featuring way more firepower, mobility, and protection. They were a lot more expensive than previous models, but this was nullified by their shockingly impressive performance in the battlefield. The T390 series defines a new set of innovations set by the countless number of new discoveries after the battle of terra, and combines it with their centuries old battle doctrines that are still effective up to date.

## History

### **Development**

As the 3rd Alien War rages on in the favor of the Ostroni, even the ground war is in their favour. The new swordfury tanks, despite their superior abilities compared to previous MBTs, are heavily outmatched by Ostroni heavy armour, and performs adequately against regular Ostroni MBTs. This factors, combined with newer Ostroni energy bolts that destroy the tank's internals after penetrating by exploding, lead to horrible amounts of EUF tank crewmen losses. The compartments inside the tanks werent able to withstand the explosion, causing a chain reaction that would destroy all other modules inside the tank and killing all the crew inside. This made EUF engineers start designing on a new MBT that would solve the problem of low crew survival rates, while not making the tank too big for current main battle tank factories to ease production. This project however was delayed further by the fact most of the EUF population was evacuated to the Saggitarius Dwarf Galaxy, and their attention was instead diverted to establishing new tank factories to replace those lost to the Ostroni offensive.

### **Prototyping and Trials**

The EUF was capable of creating military vehicle designs in a very short time and it wasn't until a few days until a prototype of the T390 was ready. It had a new design until the previous MBTs which showed reused designs from the first alien war and the following era. The requirements of the tank, like tough armour, powerful cannon, and lightning fast speed were met, infact surpassed the average. Tests on up armored swordfury battle tanks totally pulverised the tanks, leaving nothing but a few bits of metal or even none at all. They were capable of destroying the previous Legionnaire tank model with ease. The T390A's twin supernova grav cannons were able to pierce through 3.5 meters of synthetic NP at a range of 1,000 meters, meaning within a kilometer it can take out another T390, which means even if the Ostroni were to develop a counter, it wont still match up against the EUF MBTs. Armour held up against virtually any anti-matter cannon from previous tanks, as well as even heavy cannons like sun launchers, the closest equivalent of the EUF to the dreaded warpblackhole cannons.

The speed however was a massive improvement. Traverse speeds were slightly slower due to the heavier tanks but the forward and backward speed outmatched all previous tank models for standard battle tanks. Forward speed is at max 210 km (or 131 miles) per hour, and 160 km (100 miles) per hour reverse speed.

Powered by a 46,000 horsepower zeolyte atom collider engine, this gives it an impressive 368 hp/ton power to weight ratio. It could hypothetically go alot faster but its top speed is limited as to make it not too hard for the driver as well as to lessen strain on the tracks, which can reach up to 700 degrees celcius and shorten its lifespan. This flaws would soon be fixed however when the battle model was ready.
