BACKGROUND
 The VHT-1 “Spartas” was developed by the United Earth Government in 2015 to fill the armored reconnaissance role, a role which had previously been carried out by the VBT-1 "Centaur"; however, by 2015 technological improvements had made the design dangerously obsolete. The new design was required to have superior maneuverability over the older RDF Destroid and VBT-1 “Centaur” models but retain the armor and firepower to directly confront the most powerful Zentraedi mecha. Two designs were placed forwarded as prospective candidates. The first was an upgraded version of the venerable Centaur, dubbed the VBT-1A1 “Centaur-II” and the other was the VHT-1 “Spartas” hovertank. Although the Centaur-II provided protection for the crew in all modes and possesses slightly greater firepower, the VHT-1 “Spartas” ultimately won the competition with its greater maneuverability and dedicated battloid mode. The VHT-1 “Spartas”, like most of the other variable fighter designs, has three modes each of which fulfills a different role for the unit. The hovertank is used when the unit is operating in its reconnaissance role and provides the Spartas with the highest speed and greatest maneuverability. The while in hovertank mode the Spartas is powered by four Pratt and Whitney HJ-800 fanjets, which propels the mecha to speeds up to 161 kph. The guardian, also known as tank, configuration sacrifices speed but allows the unit to fire its 105mm smoothbore cannon with improved accuracy and allows the autoloaders to reload the weapon. Finally battloid mode, gives the Spartas all the advantages of a humanoid form.
The Spartas is armed with an impressive load out of direct attack weaponry. The primary weapon for the VHT-1 is a 105mm smoothbore cannon mounted in an armored housing on the right arm. The 105mm cannon can only be fired while the mecha is in guardian or battloid mode. Ammunition is supplied to the cannon via an autoloader which is only functional while the Spartas is in guardian mode. Hence, while in battloid mode the mecha can only fire the shell that is currently loaded. The type of ammunition is chosen by the pilot or picked automatically by the onboard computer with the autoloader providing up to 20 shells per minute.
The left armored housing mounts an Oerlikon PP-36 triple-barreled plasma pulse cannon capable of firing 5 MJ bursts of annihilation disks, similar to those found on Invid mecha, out to an effective range of 1200 meters. The weapon is provided plasma directly from the main protoculture energizers, which allows the weapon to fire up to twenty bursts per minute. Unlike the 105mm smoothbore, the PP-36 can fire either in battloid or guardian without penalty but cannot be used in hovertank mode.
The primary weapon of the VHT-1 in battloid is a single EU-11 laser gun pod, which is carried in either arm and mounted in the center of the unit while in hovertank. The EU-11 cannot be used while the Spartas is in guardian, as it is mounted underneath and blocked by the units internal structure. The EU-11 is powered directly from the main protoculture energizers and can fire 13.5 MJ bursts of laser energy out to an effective combat range of 3.5 km.
The Spartas was armored with the latest generation of Chobham low-mass composite plate providing immunity from all anti-personnel and light anti-mecha weaponry. The armor was so resistant that the unit could be disabled only by multiple hits from medium (55mm) or heavy anti-mecha weaponry. In addition to the heavy armor, the Spartas was provided with two heavily armored arm shields in which the 105mm smoothbore and PP-36 cannons were mounted. These arm shields could be used to parry incoming attacks while the Spartas is in battloid mode and are capable of deflecting attacks that could penetrate the main armor and thus disable the unit. The heavy armor and arm shields give the Spartas nearly 50% the armor protection over the earlier RDF series of Destroids.
The VHT-1 “Spartas” was declared the winner of the UEG armored reconnaissance competition and the first combat squadrons of Spartas were formed in late 2015. Although, the Spartas design was largely viewed as a success, only the Armies of the Southern Cross mass-produced the VHT-1. The Robotech Defense Forces, and the later Robotech Expeditionary Forces, viewed the Spartas as overly complicated and not worth the expense of having a ground Veritech when the next generation of Destroid designs were arguably as or more effective. Only 515 units were produced for the RDF/REF, however, they formed the famous Wolfe pack achieving great success in South America and later during the Sentinel campaigns.
Where the RDF/REF largely shunned the design, the Armies of the Southern Cross embraced the Spartas, so much so that the VHT-1 “Spartas” became intricately linked with the 2nd Robotech War as the VF-1 did with the 1st. Over 7,500 VHT-1 were produced for the Armies of the Southern Cross from 2015 until the start of the 2nd Robotech War in 2029. After fourteen years in service the VHT-1 design remained largely unchanged; however, with the initial contact with the Robotech Masters, the ASC high command came to the realization that the VHT-1 design would have to be updated.
Rushed into production the VHT-1A1 was the first major update to the Spartas design in nearly fourteen years. The –1A1 design replaced the problematic 105mm smoothbore cannon with a 220mm laser cannon which is provided power from four dedicated protoculture canisters. The weapon can fire 31.5 MJ bursts of energy out to an effective combat range of over 4 km. While in guardian mode the laser cannon is hooked directly into the main protoculture energizers, which provide enough power for up to 32 shots per minute; however, in battloid the weapon is extremely unwieldy and limited to 8 shots per minute. In addition to the enhanced weaponry, the –1A1 model was provided with upgraded armor and electronics over the older model. The –1A1 model proved to be an extremely effective design and over 1,000 units were produced in the first six months of the 2nd Robotech War.
As the war progressed, the ASC decided that another set of upgrades was necessary. The most glaring fault with the Spartas was the lack of protection for the pilot while in guardian or hovertank mode. During the last months of the war the –1A2 and –1A3 models were introduced with armored hoods and mounts for rocket thrusters to provide additional thrust for spaceborne operations. The –1A2 model were not new units, but were upgraded original VHT-1 models with new electronics. A total of 650 units were upgraded from the VHT-1 to VHT-1A2 standard during the 2nd Robotech War. VHT-1A3 models were either upgraded from the –1A1 standard or newly built models. A total of 745 VHT–1A3 models were produced during the last two months of the war, 503 being upgraded –1A1 models and 242 newly constructed.
After the end of the 2nd Robotech War, production of the –1A3 continued during the seven months leading up to the Invid Invasion of March 2031, albeit at a much reduced rate of only 15 per month. Only slightly over 1,000 VHT-1 Spartas of all models had survived the end of the 2nd Robotech War, and were available for duty against the incoming Invid. Although the remnants of the Armies of the Southern Cross fought valiantly, predictably most of Earth’s defenders were destroyed during the first 48 hours of the assault. REF intelligence estimates that only 200 VHT-1 Spartas survived the onslaught and many of these found their way into various resistance groups. During the subsequent years of Invid occupation, most of the remaining units were destroyed or were forced into retirement due to lack of spare parts and only a handful were still operational by the time the Earth Reclamation Forces arrived.
