The RQ-21 Blackjack is a versatile, twin-boom UAV designed for tactical reconnaissance and surveillance missions, offering runway-independent operations.
The Boeing Insitu RQ-21 Blackjack, also known as the Integrator, is a small tactical unmanned aerial vehicle (UAV) developed for reconnaissance, surveillance, and target acquisition missions. It features a twin-boom, single-engine design with a wingspan of 16 feet (4.9 meters) and a length of 8.2 feet (2.5 meters). The UAV has a maximum takeoff weight of 135 pounds (61 kilograms) and can carry a payload of up to 39 pounds (17.7 kilograms). Powered by a 8.5 horsepower (6.3 kW) engine, the RQ-21 achieves a cruise speed of 63 miles per hour (101 kilometers per hour) and has an endurance of over 16 hours. It operates at altitudes up to 19,500 feet (5,944 meters) and has a line-of-sight range of 55 nautical miles (102 kilometers). The UAV is launched via a pneumatic launcher and recovered using a Skyhook system, eliminating the need for runways.
History of Development
In the early 2000s, the U.S. Navy identified a need for a Small Tactical Unmanned Air System (STUAS) to enhance ISR capabilities for naval and marine operations. Existing systems lacked the versatility and endurance required for modern combat scenarios. To address this gap, the Navy initiated the STUAS program, seeking a UAV that could operate from both land and sea without the need for runways.
In June 2010, after evaluating several contenders, the Navy selected Insitu’s Integrator design over competitors such as the Raytheon Killer Bee, AAI Aerosonde, and General Dynamics/Elbit Systems Storm. The Integrator was chosen for its modularity, endurance, and runway-independent launch and recovery systems.
The RQ-21A Integrator conducted its maiden flight on July 28, 2012. By September 10, 2012, it entered developmental testing, completing a 66-minute flight. The UAV was launched using a pneumatic launcher and recovered with the Skyhook system, which employs a vertical cable to snag the aircraft, allowing for operations without traditional runways—a critical feature for naval deployments.
On February 10, 2013, the Integrator achieved its first at-sea flight from the USS Mesa Verde, a San Antonio-class amphibious transport dock, demonstrating its maritime operational capabilities. Following this, on February 19, 2013, Insitu completed the first flight of the RQ-21A Block II, which featured enhancements such as a 121-pound (55-kilogram) weight and a two-hour flight duration. This variant was controlled by a new ground control system designed to integrate dissimilar UAV systems, and it incorporated sensors from the Nighteagle, the night version of the ScanEagle, optimized for high-temperature environments.
The Department of the Navy granted Milestone C approval on May 15, 2013, authorizing the start of low-rate initial production. This milestone marked the transition from development to production and deployment phases. Subsequently, on June 12, 2013, the RQ-21A completed its first East Coast flight from Webster Field Annex, validating updates including software enhancements, fuselage modifications, and improved camera systems. Integrated Operational Test and Evaluation (IOT&E) was scheduled for October 2013.
In September 2013, the Integrator was officially designated as the RQ-21A Blackjack. The U.S. Navy awarded Boeing Insitu an $8.8 million contract on November 28, 2013, for one low-rate production aircraft in preparation for full-rate production. By January 2014, the first low-rate production RQ-21A Blackjack began IOT&E for the U.S. Navy and Marine Corps, with testing conducted over several months to assess its effectiveness in realistic combat conditions. The Navy ordered three Blackjack systems in December 2014, and by July 2015, had received two systems. In July 2018, the Marines phased out the RQ-7 Shadow in favor of the Blackjack, highlighting its operational success and reliability.
Design
The RQ-21 Blackjack features a twin-boom, high-wing monoplane design, providing stability and ample space for payload integration. Its modular architecture allows for rapid reconfiguration to accommodate various mission-specific payloads, enhancing its versatility.
Airframe and Dimensions:
- Wingspan: 16 feet (4.9 meters)
- Length: 8.2 feet (2.5 meters)
- Maximum Takeoff Weight: 135 pounds (61 kilograms)
- Payload Capacity: Up to 39 pounds (17.7 kilograms)
The airframe is constructed from composite materials, balancing strength and weight to optimize performance and endurance. The twin-boom configuration supports the tail assembly, contributing to aerodynamic stability.
Propulsion:
The UAV is powered by a single 8.5 horsepower (6.3 kW) engine, driving a two-blade propeller mounted at the rear in a pusher configuration. This setup reduces noise and enhances aerodynamic efficiency.
Launch and Recovery Systems:
The RQ-21 Blackjack is runway-independent, using a pneumatic launcher for takeoff. This system accelerates the UAV to flight speed without the need for a traditional runway. For recovery, it employs the Skyhook system, which captures the aircraft mid-air using a vertical cable. This system minimizes the operational footprint and allows deployment from confined spaces, such as naval vessels or forward-operating bases.
Payload and Sensors:
The modular payload bay accommodates various sensors, including:
- Electro-optical and infrared cameras for day and night imaging.
- Synthetic aperture radar for ground mapping and moving target detection.
- Communications relay systems for extending tactical networks.
- Electronic warfare and signal intelligence equipment.
The modularity of the payload systems allows for rapid adaptation to mission requirements, making the Blackjack a versatile asset.
Advantages and Drawbacks:
Advantages:
- Runway independence: Ideal for maritime and remote operations.
- Modularity: Rapid payload integration enhances versatility.
- Compact size: Simplifies transport and deployment.
Drawbacks:
- Limited payload capacity compared to larger UAVs.
- Vulnerability to adverse weather conditions due to its small size.
Performance
The RQ-21 Blackjack delivers robust performance in tactical ISR operations, supported by its design and propulsion systems.
Specifications:
