The S2R-660 Archangel Border Patrol Aircraft (BPA) is a light attack and surveillance aircraft designed and produced by the US-based aircraft manufacturer IOMAX. In its latest effort to evolve the Border Patrol Aircraft concept, IOMAX has partnered with Thrush Aircraft to jointly produce the Archangel, a sophisticated, production, S2R 660 Thrush purpose-built aircraft. This aircraft is manufactured off the manufacturing line to perform day/night ISR utilizing the 660 Thrush frame as its host. The Archangel is capable of providing real time intelligence data from altitudes as high as 20,000+ ft, delivering precision air strikes with minimum collateral damage. The IOMAX Archangel Block 3 Border Patrol Aircraft was unveiled during Paris Air Show 2013 and performed its maiden flight in July 2014.
The Archangel is the latest version of IOMAX’s Block 1 and Block 2 AT-802 turboprop that is currently fielded by the UAE and Jordan. In October 2014, the UAE has signed a contract to procure “an enhanced squadron” of IOMAX Archangel Border Patrol Aircraft (BPA).
UAE’s fleet will now be replaced by 24 Archangel aircraft. IOMAX has offered its Archangel Block 3 Border Patrol Aircraft (BPA) to Turkey, and to the Philippine Air Force (PAF) as a replacement for its ageing Rockwell OV-10 Bronco counterinsurgency fleet. IOMAX has also received interest from countries such as Angola, Niger, and the Ivory Coast, among others.
The Archangel has fully integrated night vision capable front and rear glass cockpits. The aircraft features easy access for maintenance in the field or fixed base operations. The Pratt & Whitney PT6A-67F engine powers the MTV-27 MT Propeller 5-Blade propeller allowing for shorter take-off distances, reduced audible signature, increased rate of climb and cruise speed, and overall smoother operations. With a large wing area designed for heavy payload capacity, Archangel has a fixed reinforced landing gear for hard-landing survivability on rough field operations. Featuring unmatched operational flexibility, the multi-mission Archangel can operate up to 25,000 feet (with oxygen), and has 4,800 lb (2177 kg) external stores payload capacity. Source iomax.net

Archangel Block 3
Archangel Block 3 Border Patrol Aircraft (BPA)
The IOMAX Archangel Border Patrol Aircraft is fitted with front and rear night vision compatible (NVG) glass cockpits equipped with CMC’s Esterline Cockpit 4000 avionics suite. Three 5in x 7in multi-function displays (MFD) and one up front control panel (UFCP) are provided in the front cockpit whereas the rear cockpit is fitted with one 5in x 7in MFD and one UFCP.
The Archangel border patrol aircraft is based on the Thrush Aircraft’s S2R-660 (710) airframe. It features a large wing area and a fixed, reinforced landing gear, which facilitates safe take-off and landing on unimproved, dirt, grass and gravel surfaces. The airplane has a length of 11m and a wing span of 17.4m. It can carry 2,177kg of payloads externally, and has day and night operational capability. A crew of two are accommodated on the airplane in a dual control, tandem seat configuration to render increased visibility. As well as being blended to the fuselage, the Archangel’s tandem twin-cockpit has been moved forward and slightly stretched to increase the view forward and down for the pilot and the space available for the rear crew-member.
The Pratt & Whitney PT6A-67F engine (1,796 eshp and 1,700 shp) powers the MTV-27 MT Propeller 5-Blade propeller allowing for shorter take-off distances, reduced audible signature, increased rate of climb and cruise speed, and overall smoother operations. In addition to increasing the aircraft’s speed, its range and endurance have been significantly improved by converting the ‘hopper’ space in the nose (used for carrying crop spraying chemicals in the agricultural airframe) into a main fuel tank that can hold 338 US gallons. In addition to the two 184 US gallon tanks in the wings, this extra fuel takes the Archangel’s range out to 1,350 n miles (with stores), compared to approximately 450 n miles for the baseline S2R-660 (clean) platform.
MASE pod for Archangel
Terma has provided IOMAX USA with the self-protection suite – based on its Modular Aircraft Self Protection Equipment (MASE) pod – for the Archangel intelligence, surveillance, and reconnaissance (ISR) light attack aircraft being supplied to the UAE.
The self-protection suite selected for the Archangel uses twin MASE pods (fitted on underwing hardpoints port and starboard) configured with missile warning sensors and countermeasures dispensing systems, all tied into Terma’s cockpit-mounted ALQ-213 Electronic Warfare Management System.
Based on Thrush Aircraft’s S2RT660 single-turboprop aircraft, the Archangel has been designed to meet requirements for ISR, border protection, counter-insurgency, armed reconnaissance, close air support, forward air control, and combat search and rescue.
Fitted with a high-performance electro-optical/infrared reconnaissance and targeting capability, and six underwing stores hardpoints, the aircraft is able to deliver a wide range of precision-guided munitions including 70mm laser-guided rockets, AGM-114 Hellfire missiles, and GBU-58 and GBU-12 Paveway II laser-guided bombs.

AN/ALQ-213 EW Management Unit
The Electronic Warfare Management System (EWMS) ALQ-213 product family is the core system of Terma’s integrated Electronic Warfare (EW) systems solutions. As a subsystem and aircraft independent system, the ALQ-213 integrates individual subsystems into one combined system. The pilot has one single interface to all self-protection subsystems which results in increased survivability and reduced stress on the pilot in critical situations.
In collaboration with a large number of end users and aircraft manufacturers, the performance and capabilities of Terma’s EWMS have continuously been expanded over the past two decades. Today, the product represents the most common and mature Electronic Warfare management system in the market.
One Coherent System Solution
The ALQ-213 management system manages all subsystems automatically and displays alerts, status, etc. as one coherent system instead of a number of individual subsystems.
Terma’s management system is unique in the sense that, on one hand, it creates an integrated systems solution, but on the other hand, it does not need to be tightly integrated into the aircraft’s main control software. This means low integration costs as well as increased flexibility for the users.
Commonality across Platforms
The uniqueness of the ALQ-213 family of controllers is that the same product can be used across a mixed fleet of aircraft (fighters, helicopters, and fixed wing transport aircraft) because the products have been developed for generic solutions rather than dedicated platforms.
Freedom of Choice
The ALQ-213 allows for integration of any EW subsystem (Radar-, Missile-, Laser Warning, Direct InfraRed CounterMeasures systems, Jammers, Decoys, and Dispensers) enabling us to deliver the solution that best meet operational requirements and budget.
A Total EW Package
As a mature product, the ALQ-213 product family comes with all necessary tools supporting all phases of the flight from planning, recording, training, and analysis for continuous optimization of the operational performance. Source terma.com

TERMA AN/ALQ-213 missile warning system
Missile and Radar warning systems
To meet different levels of capabilities, two groups of controllers have been developed:
- The EW Management Unit (EWMU) combined with the Tactical Data Unit (TDU)
- The Defensive Aids Controller (DAC)
The EWMS is fielded on +2.000 aircraft all over the globe. Leading F-16 countries operate the system across their fleets of aircraft. The European Participating Air Forces (EPAF) have been driving the continuous development of the capabilities in the system which today include Embedded Training and Electronic Combat Adaptive Processing. The EWMS has been optimized with respect to size, functionality, and effectiveness at use.
The new and more powerful version of the EWMS will be introduced in two different configurations:
The ALQ-213 RMP: form-fit with the existing 213 but much more powerful and capable of meeting future requirements to interfaces, sensor fusion, and hosting of third-party subsystem software.
ALQ-213 MUP: same form-fit as the existing 213 but without manual interface panel. This version is designed to interface with glass cockpit and for installation outside the avionics bay.
The DAC represents an integration of subsystems into one box, i.e.:
- the EW management system
- recording capability
- programmable interference blanking unit
- provision for hosting of third-party printed circuit boards and software to allow for cost-effective upgrades over the total life of the aircraft
- supporting interface to glass cockpit but can be operated using a dedicated remote control panel.
