N202-088       TITLE: Advanced Low-Level Parachute System


RT&L FOCUS AREA(S): General Warfighting Requirements (GWR)



OBJECTIVE: Develop a low-level parachute system to insert forces while allowing the aircraft to fly faster and lower than current systems.


DESCRIPTION: Current military low-level parachute systems take one of two paths. Non-maneuverable systems allow for many parachutists in the air or maneuverable systems with limited glide capabilities. Current systems were designed to operate in a mountainous environment and do not emphasize a lower operational altitude. The current systems utilize a front mounted reserve that interferes with the wearing of combat equipment. Current building, antenna, span, and earth (BASE) parachute systems are regularly used at altitudes of less than 500 ft. above ground level (AGL) with initial velocities, both horizontal and vertical, of zero. Advances in the use of lightweight fabric and innovative sewing methods allow BASE parachute systems to minimize system weight.


An Advanced Low-Level (ALL) parachute system could combine the innovations of the commercial BASE parachute systems, paraglider reserves, and possibly static line military systems. The design needs to provide a consistent on-heading opening while dissipating the energy from the exit speed and allowing for glide to a small drop zone. The challenges of speed, weight, and altitude pose the greatest risk to a successful design.


Developing an ALL parachute system could replace the current low-level parachute system. The ALL parachute system could require a different sized system to meet the weight and range requirement. The ALL parachute system must include reliability and safety systems for personnel operations. Proposed systems should meet the following performance specifications:


Minimum exit altitude:� Threshold (T) 750 ft. AGL Objective (O) 500 ft. AGL

Dropzone height:� (T) 2,000 feet Mean Sea Level (MSL) Objective (O) 4,500 ft. MSL

Weight capacity not including ALL system:� (T) 105-300 lbs.� (O) 105-330 lbs.

Aircraft exit speed:� (T) 145 knot indicated air speed (KIAS) (O) 150 KIAS

Dropzone size:� (T) 360m X 270m (O) 240m X 180m


PHASE I: Develop concepts for an ALL parachute system meeting the requirements described above. Demonstrate the feasibility of the concepts in meeting Marine Corps needs and establish the concepts for development into a useful product for the Marine Corps. Use material testing and analytical modeling to establish feasibility, as appropriate. Provide a Phase II development plan with performance goals and key technical milestones and that addresses technical risk reduction.


PHASE II: Develop a prototype for evaluation to determine its capability in meeting the performance goals defined in the Phase II development plan and the Marine Corps requirements for the ALL parachute system. Demonstrate system performance through prototype evaluation and modeling or analytical methods over the required range of parameters including numerous deployment cycles. Use evaluation results to refine the prototype into an initial design that will meet Marine Corps requirements. Prepare a Phase III development plan to transition the technology to Marine Corps use.


PHASE III DUAL USE APPLICATIONS: Support the Marine Corps in transitioning the technology for Marine Corps use. Determine its effectiveness in an operationally relevant environment. Support the Marine Corps in test and validation to certify and qualify the system for Marine Corps use.

Low level parachutes are currently used primarily as recreational in the United States. New parachute systems could be used by airborne firefighting services to increase reliability and improve access to remote fires. New designs could be utilized by companies interested in delivering items in Class G airspace.

The Navy Topic above is an "unofficial" copy from the overall DoD 20.2 SBIR BAA. Please see the official DoD DSIP Topic website at for any updates. The DoD issued its 20.2 SBIR BAA on May 6, 2020, which opens to receive proposals on June 3, 2020, and closes July 2, 2020 at 12:00 noon ET.

Direct Contact with Topic Authors. During the pre-release period (May 6 to June 2, 2020) proposing firms have an opportunity to directly contact the Technical Point of Contact (TPOC) to ask technical questions about the specific BAA topic.

Questions should be limited to specific information related to improving the understanding of a particular topic�s requirements. Proposing firms may not ask for advice or guidance on solution approach and you may not submit additional material to the topic author. If information provided during an exchange with the topic author is deemed necessary for proposal preparation, that information will be made available to all parties through SITIS (SBIR/STTR Interactive Topic Information System). After the pre-release period, questions must be asked through the SITIS on-line system as described below.

SITIS Q&A System. Once DoD begins accepting proposals on June 3, 2020 no further direct contact between proposers and topic authors is allowed unless the Topic Author is responding to a question submitted during the Pre-release period. However, proposers may submit written questions through SITIS at, login and follow instructions. In SITIS, the questioner and respondent remain anonymous but all questions and answers are posted for general viewing.

Topics Search Engine: Visit the DoD Topic Search Tool at to find topics by keyword across all DoD Components participating in this BAA.

Help: If you have general questions about DoD SBIR program, please contact the DoD SBIR Help Desk at 703-214-1333 or via email at [email protected]
