Reliable electrical and mechanical performance are crucial for military applications that use MIL-STD-1760 assemblies to ensure mission critical success. But, our customers have told us that they have to replace frequently standard umbilical assemblies that use screw-on MIL-DTL-38999/31 land yard connectors because they don’t withstand pylon installation and operation.
Guaranteed 100 Store Releases
Introduced to NATO in the mid-1990s, Gore identified a need to provide a reliable, easy-to-use umbilical assembly with a connector system that did not fail during operation. GORE MIL-STD-1760 Assemblies combined with the Harris Field Replaceable Connector System (FRCS) were successfully qualified against specification with proven, consistent disconnect loads and certified for more than 100 ejected releases. In fact, this assembly with the FRCS has delivered more than 3,500 successful store releases on many airborne platforms such as:
- A-10 Warthog
- F-15e, F-16 and F-35
- Super Lynx
- Tornado GR4
Also, our assemblies with the Harris FRCS provide outstanding electrical and mechanical performance in demanding aerospace environments such as rigorous installation and wide temperature ranges.
Easy Pylon Installation
Our MIL-STD-1760 assemblies can withstand repeated flexing without mechanical or electrical failure and have a proven flex life of more than 100,000 flexes for easy routing in limited spaces of aircraft pylons. With a robust, yet flexible construction, they reduce downtime and life-cycle costs because they don’t have to be replaced after each use.
Also, our assemblies can be attached to and removed from ASI (Aircraft Store Interface) and MSI (Mission Store Interface) while operating in an NBC (Nuclear Biological Chemical) environment in accordance with MIL-STD-1472, Paragraph 4.10. The technology enables fast and easy connector system replacement while maintaining proven product performance.
GORE® MIL-STD-1760 Assemblies have a proven flex life of more than 100,000 flexes for easy routing and installation.

Features & Benefits
For more than 40 years, Gore has delivered reliable solutions to the military aerospace industry. Our cables and materials are specified on many of today’s platforms and play a vital role in system performance and reducing overall risk to programs. We’ve provided high-performance solutions for complex packaging and installation that have been selected for the Joint Strike Fighter (JSF) F-35 Lightning II Program.
GORE MIL-STD 1760 Assemblies combined with the Harris Field Replaceable Connector System (FRCS) provide features that make them an ideal replacement for standard umbilical assemblies and connectors.
- average release load of 550 + 85N (125 + 20 lb/f)
- maximum release load of 880N (200 lb/f)
- fail-safe operation up to 45˚ pull-off angle
- consistent operation up to 75 mm of lanyard slack
- all above tested during ejected pit releases up to 5 m/s
- operational temperature range of -60˚ C to 150˚ C
- Certified for 500 manual disconnects
GORE MIL-STD 1760 Assemblies provide manufacturers with many benefits that improve electrical and mechanical performance such as:
- Harris FRCS with jam-free, push-on/pull-off connection that has been tested and guaranteed 100 ejected releases
- superior electrical and mechanical performance in extreme environments
- proven flex life more than 100,000 flexes for improved installation and easy routing
- robust construction for reduced life-cycle costs because they don’t have to be replaced after each use
- a variety of connector options including standard shell size 25 and 17 store disconnects.
- a variety of standard cable assembly Class I and II offerings, or customized versions to meet any aircraft integration requirements
- fully qualified, tested and flight-proven on many airborne platforms for reduced downtime, increased aircraft availability and lasting performance

Gore and Harris performed validation testing on GORE MIL-STD-1760 Assemblies with the Harris Field Replaceable Connector System (FRCS) compared to standard umbilical assemblies that use screw-on MIL-DTL-38999/31 land yard connectors. We configured the test on stores with racks that were adjusted to represent accurately various pylon stations, including retention methods. Then, we captured the data during the test to validate connector loads and store velocity.
Our results showed that 1 out of 10 new standard umbilical assemblies with screw-on connectors separated within the specification load. But, GORE MIL-STD-1760 Assemblies with the Harris FRCS delivered consistent disconnect loads and can guarantee 100 fully instrumental drops.
GORE MIL-STD-1760 Assemblies meet the stringent specification requirements of military aircraft. They have undergone substantial qualification testing to ensure they meet the specifications of the most current standards and our customers’ requirements.
