DRAFT Industry Performance Specification (P-SPEC) for SRR Mk 1

Overview: Warfighters on today’s battlefield are facing an adversary that is well-equipped with cheap, easy to access, highly capable drones that place our troops at a tactical disadvantage. In direct response to this technical challenge, the U.S. Army intends to develop and field the Short Range Reconnaissance (SRR) platform. The SRR is a small, rucksack portable, vertical take-off and landing (VTOL) platform that provides the platoon with an organic, rapidly deployed intelligence, surveillance, and reconnaissance (ISR) capability to provide situational awareness beyond the next terrain feature.

The intention of this document is to provide industry with high level system performance requirements for SRR to constrain technical solutions and allow for planning and trade-off analysis ahead of the SRR Area of Interest (AOI) (i.e., "solicitation"), which is targeted for released in Q2 of FY19.

The UA shall be capable of vertical take-offs and landings (VTOL)

The UA flight characteristics desired (target capabilities): 
30 Minute Flight Endurance 
3 km operational range 
8,000 ft. Service ceiling 
Operate in 15 knot winds or greater 
Manual and semi-autonomous/waypoint flight modes 
Programmable mission and loss link procedures

UA assembly and disassembly should take 2 minutes or less by a single person (target)

The UA shall be delivered with an Operators manuals and field repair kit with minimal use of special tools

The UA airframe including battery and payload shall be able to fit within case(s) that occupy a maximum volume of 576in3 with total takeoff weight not exceeding 3lbs. (target)

The UA shall use an open communications and video protocol.

The UA should use an open autopilot software stack.(target)

The UA computer hardware must be scalable and provide flexibility to integrate with a variety of payload configurations, continually be developed, and receive upgrades.

The UA payload shall be a modular design capable of EO and IR for both FMV and Still image capture.

The UA should have the capability to enable situational awareness of people and vehicles at standoff ranges of 300m (EO) and 200m (IR). (target)

The UA shall provide still images with a minimum of 16MP (target) resolution and formatted in JPEG.

The UA shall provide High Definition (target) FMV products formatted as a H.264 elementary stream video within a MPEG2 Transport Stream.

The UA control and video latency shall be minimized for sufficient safe operation of the UA in confined areas.

The UA shall be integrated with a Government furnished common controller hardware and software (QGroundControl)

The UA should be reasonably inaudible at an autonomous steady-state cruise at 200ft AGL with a background noise of a running vehicle. (target)

The UA should be durable and reliable enough to complete 25 operationally relevant missions with minimal operator level maintenance. (target)

The UA should be able to operate within IP-53 standards and in temperatures ranging from -32F to 110F (target)

The UA should reduce operator workload through autonomy (eg optical flow, obstacle avoidance, image stabilization) and self-diagnostic features. (target)

The UA should be made as secure as commercially feasible from interference or cyber-attacks from third parties. (target)

Price point for airframe is $2K and $2K for optical sensor package. (target. Airframe price does not include radio)

The over the air communications between the UA and the GCS should be encrypted at AES-256 (target)

Radio: The UA communications shall operate within all of the following frequency bands; 1625-1725MHz, 1780-1850MHz, and 2025-2110MHz. (target) The occupied bandwidth shall be 2.5MHz or 5MHz, selectable by the user. (target) The Government will accept an interim communications system that operates within the ISM bands at variable channel widths. The UA communications subsystem shall support all other requirements specified in this document (range, resolution, etc).

Note 1: Requirements noted by “(target)” state minimums and maximums that are not absolute thresholds. They are approximate target performances that, within reason, should be included in capability and cost tradeoffs. Requirements not noted by (target) are firm requirements.

Note 2: This document is subject to change based on evolving requirements and industry feedback. Please send any feedback to

Note 3: SRR Mk1 designates the initial UAS that will be fielded for the SRR program. Future variants are possible but currently unplanned.
