The Easun Industria J52 Arcángel (Carlosian: archangel) is a tilt-wing heavy gunship based off of the O97 Vociférar transport aircraft. As a tilt-wing aircraft, it is able to rotate its wings either horizontally or vertically, making it fully capable of vertical and/or short take-off and landing (V/STOL) operations. This ability gives it many advantages over comparable attack aircraft like the Lockheed AC-130, including the ability to hover and land or take off in areas that lack a runway for conventional planes. It also possesses superior fuel efficiacy and range when compared to a conventional helicopter gunship.

Its primary armament is a two-barrelled 105 mm gun-howitzer located in a turret at the rear of the aircraft, which can be used either as a means of fire support or as a mobile artillery piece. Other armaments include dual 20 mm three-barrelled autocannons, and hardpoints that can be fitted with a variety of rocket pods, missiles or gunpods. The turret is modular, and variants with alternative armaments serve in a limited capacity with Carlosian forces. One such variant swaps the 105 mm howitzer for a six-tube launcher for a powerful 302 mm demolition rocket-propelled munition (guidance optional), intended to obliterate enemy fortifications or rapidly deliver suppressive firepower.

J52 Arcángels are mainly fielded by the Carlosian Army, though in recent years they have found service with large private military companies, most notably Conquistador Security Consulting.

Development

After the O97 Vociférar entered service in the early 2000s, Carlosian military officials, impressed by its durability and utility, sought to expand further on the design. Several proposals were put forward by the Carlosian aviation industry, with Easun Industria's proposal for a heavy gunship easily winning out. In 2009 a design team led by veteran aeronautical engineer Jenaro Estell presented a prototype of the concept.

Design

Armament

The primary armament of the J52 Arcángel is a twin 105 mm howitzer mounted in a turret to the rear of the aircraft. It can fulfil a number of roles, including providing direct fire or alternatively operating as a highly mobile fire-and-displace artillery piece. It is remotely operated by a gunner. The turret is loaded automatically and has storage for approximately 50 rounds. The design is an evolution of similiar, self-contained turrets for naval artillery. An onboard artillery computer allows the operator to use satellite-based radionavigation to select co-ordinates for the turret to automatically lay down suppressive fire upon, the turret correcting itself continuously as the aircraft moves.

Additionally, it is armed with duel front-facing two-barrelled 40 mm autocannons. Attached to each autocannon is a 40 mm grenade launcher. They can switch between automatic, semi-automatic and burst-fire modes, and have a limited ability to traverse vertically.

Also, it is armed with six launch tubes suitable for dual-purpose missiles (e.g ADATS). Alternatively the launchers can be fitted with canisters containing smaller missiles. For example, it may carry up to eighteen S854 Acechar multi-purpose missiles, with a canister containing three missiles packed in each tube. This configuration is intended for use in COIN operations against lightly-armoured or unarmoured vehicles, or against swarms of hostile UAVs.

To the rear of the aircraft are two 20 mm three-barrelled point-defence systems, primarily intended to destroy hostile anti-air missiles, aircraft and UAVs, though they can also be used to target land-based enemies. They are each guided by an extremely high frequency (EHF) passive electronically scanned radar which can detect and track targets out to beyond TBD km. Target acquistion is provided by a TBD radar. Additionally, an electro-optical device is fitted to each PDS, enabling the systems to operate without the need for radar emissions, though at the expense of capability. It is independently capable of detection, acquisition, and tracking. Alternatively, it can assist the radar arrays with their operation.

Avionics

A pair of side-scanning radars are located at the nose of the aircraft. Other systems include avionics for detecting the launch of missiles and counter-battery radar.
