STATEMENT OF WORK

FOR

CAMOUFLAGE NETTING AND EXPEDITIONARY LIFTING STRUCTURES

(CNELS), OPERATIONAL TEST SUPPORT, AND

JOINT TECHNOLOGY TRANSITION

1.0 BACKGROUND

1.1 FY19-23 Camouflage Vehicle Mesh

This Statement of Work (SOW) sets forth the requirements for the Naval Research Laboratory, Signature Technology Office (NRL STO), to design, develop, and deliver a set of Expeditionary

Inflatable Hangar systems (aka “X-Hangar”) with camouflage covers incorporating passive, multimodal capability for USMC and USAF aircraft. This work builds upon previous NRL efforts for obscuration and concealment of multiple types of vehicle platforms against ground and airborne sensors using camouflage netting. The next-generation camouflage vehicle mesh (CVM) covers require improved breathability and durability for increased wind and snow loads, while maintaining current multispectral obscuration performance. The inflatable lifting structures will support the improved CVM systems covering the aircraft platforms.

Throughout an FY19-23 collaboration with ONR Global TechSolutions, the NRL STO performed field-testing of Contractor-developed first- and second-generation Camouflage Netting Systems

(Gen I in FY19-20, Gen II in FY21-23). The Camouflage Netting Systems (CNS) developed under this effort are coated with specialized materials that match visible shades mimicking grass fields and tropical environments for off-airport locations. Coatings were also developed to match visible shades commonly found in concrete and asphalt for on-airport locations. The coatings exhibit an additional low-contrast capability extending to the NIR (0.7-0.9 micron), SWIR (0.9-1.7 micron), and thermal IR (3.0-12.0 micron) spectral bands by mimicking the spectral reflectance values in these respective background environments. The CVM design also incorporates optimized RF-scattering capability at appropriate levels to obscure aircraft from 360-degree detection by both airborne and unmanned aerial surveillance systems (UAS).

First-generation CVM systems lacked the required durability and contrast (blending into background) in certain spectral bands required improvement. Second generation CVM systems improved the durability and blending aspects missing in the Gen I CVM, but also lowered airflow through the covers, which limited wind flow. The research and development of the third-generation CVM under this Statement of Work will attempt to correct this attribute, along with panel design, mounting, durability, lofting, and curtain functionality to deliver correctly reinforced systems for regular use and recurring deployment for USMC and USAF aircraft

1.2 FY21-23 Inflatable Lifting Structures

In FY21, NRL STO developed an inflatable lifting structure to be used as an expeditionary shelter for aircraft (aka “X-Hangar”), and provided structural support of the CVM covering the aircraft.

The first generation X-Hangar system (FY21) was a semicircle design with a 2-ply fabric shell.

This system was very heavy to move and to lift during inflation. A second generation X-Hangar

(FY22-23) was designed with a single-ply fabric shell and parabolic shape that reduced overall weight and improved ease of lifting during inflation. The research and development of the third generation X-Hangar under this Statement of Work will attempt to improve size, weight, and power (lower SWaP) as well as improve mobility of the structure during both transport and service.

2.0 OBJECTIVES

The objectives for the third generation X-Hangar Shelter system under this SOW is to make signature and durability improvements upon the camouflage cover system, lower SWaP for the inflatable system and electronics and deliver improved systems to USMC and USAF end-users for testing and evaluation. End users shall then provide feedback in the form of an after-action report

(AAR) to NRL with suggested improvements/changes to a final X-Hangar system that will also be delivered at the end of the contract period of performance. The ultimate objective at the completion of this project is to have a product which meets the USMC and USAF requirements and is ready to transition to acquisition.

A list of project objectives is provided in Table 1.

3.0 SCOPE OF WORK

The technical approach for this contract includes building a set of initial prototype systems meeting physical and signature requirements received from USMC and USAF end-users of the system.

NRL Code 5009 Signature Technology Office will provide contracting oversight, as well as engineering for developing a material solution for improved signature management of the X-

Hangar CVM covers. The Contractor shall design and manufacture the X-Hangar camouflage covers, inflatable structure, and system electronics, respectively. Each part of the X-Hangar system will require modification to bring up to MIL-SPEC standard, as well as reducing size, weight and power (SWaP) to be more conducive to expeditionary (rapid) deployment and setup/teardown. Once the prototype systems have been delivered to the end-users and thoroughly tested, a final set of physical and signature requirements will be drafted and provided to the

Contractor to build a final set of X-Hangar systems based on these requirements. The final set of

X-Hangar systems shall also be delivered to USMC and USAF end-users.

4.7.3 Mid-wave Infrared (MWIR, 3-5µm) and Long-wave Infrared (LWIR, 8-12µm)

4.7.3.1 The aircraft cover must exhibit a thermal IR (MWIR and LWIR) signature that conceals/blends the covered aircraft with both grassy and tropical environments, providing concealment at 350m (T) and 1000m (O) from tactical ground sensors; 500 ft (T) and 1000ft (O) from aerial (UAS) sensors.

4.7.3.2 The aircraft cover must exhibit a thermal IR (MWIR and LWIR) signature

17 | 2 5 such that it obscures the aircraft IR signatures at 350m (T) and 1000m (O) from tactical ground sensors; 500 ft (T) and 1000ft (O) from aerial (UAS) sensors.

Synthetic Aperture Radar (SAR, X, Ku, and KA bands)

4.7.3.2 Capable of obscuring the aircraft from airborne synthetic aperture radar

(SAR), meaning SAR must be unable to discern/discriminate the object due to RF-scattering effects of the cover over the aircraft.

4.7.3.3 The radar Cross Section (RCS) of the CVM must have an attenuation based on the following parameters:

Table 10. Radar Cross Section (RCS) Thresholds and Objective Values for CVM

RCS Objective Minimum Average Apparent Attenuation

(RCS - dB)

O/T Threshold Objective

Radar Band Co-Channel Co-Channel C ≥ 8 ≥ 10 X ≥ 9 ≥ 10

Ku ≥ 11 ≥ 15 Ka ≥ 13 ≥ 18 W ≥ 16 ≥ 20

Durability

ASTM D 2261-13, “Standard Test Method for Tearing Strength of

Fabrics by the Tongue (Single Rip) Procedure (Constant-Rate-of-

Extension Tensile Testing Machine).”

The CVM fabric must have a minimum breaking strength of 120 force-lbs (lbf) in both warp and fill directions, based on the test method prescribed in

ASTM D 5034-09, “Standard Test Method for Breaking Strength and

Elongation of Textile Fabrics (Grab Test).”

Method for Air Permeability of Textile Fabrics.”

Enable sufficient airflow through the concealment cover to reduce and minimize sheer stress due to high winds; >25 mph (T), >40 mph (O)

18 | 2 5

Allow harmful vapors such as JP5 jet fuel, petrol, and other noxious fumes to escape easily and not be contained under the cover, eliminating breathing and respiratory hazards.
