The Boeing Insitu RQ-21 Blackjack, company name Integrator, is an American unmanned air vehicle designed and built by Boeing Insitu to meet a United States Navy requirement for a small tactical unmanned air system (STUAS).

This eliminates the need for runways and enables a safe recovery and expeditionary capability for tactical missions on land or sea.

[8] On 10 February 2013, the Integrator completed its first at-sea flight from the USS Mesa Verde, a San Antonio-class amphibious transport dock.

The Block II has the sensor from the Nighteagle, the night version of the ScanEagle, and is designed to operate in high-temperature environments.

[10] On 15 May 2013, the Department of the Navy announced that the RQ-21A Integrator received Milestone C approval authorizing the start of low-rate initial production.

[11] On 12 June 2013, the RQ-21A completed its first East Coast flight from Webster Field Annex, starting the next phase of tests for the Integrator.

This phase of testing was to validate updates made to the aircraft which include software, fuselage, and camera enhancements.

[7] The Office of Naval Research (ONR) plans to add a sensor to the Blackjack that combines an electro-optical camera, wide area imager, short wave infrared hyperspectral imager, and a high-resolution camera for use as an inspection sensor into a single payload by 2020.

It supports intelligence, surveillance, and reconnaissance (ISR) missions using multi-intelligence payloads including day and night full-motion video cameras, an infrared marker, a laser range finder, a communications relay package, and automatic identification system receivers.

Deploying the aircraft on the ground was a method to detect and fix problems early to avoid delaying the project.

EOC Blackjacks will continue to be used for training, while completion of shipboard testing is planned to result in the system's first ship-based deployment in spring 2015.
