5th Generation

The most advanced class of fighters, representing a quantum leap in capability that includes unmatched air-to-air and air-to-ground capability, dominant situational awareness, unprecedented Intelligence, Surveillance, Reconnaissance (ISR), inherent airborne electronic attack and very low observable, all-aspect stealth.

ALIS - Autonomic Logistics Information System

Infrastructure for data collection, data analysis and decision support to match fleet data to resources in real time. Read more about ALIS.

Avionics

Also known as mission systems, the integrated electronic sensors, displays and communications systems that collect and share data with the pilot and allies in other aircraft, at sea and on the ground.

CATBird - Cooperative Avionics Test Bed

A modified 737 aircraft that contains an F-35 cockpit and test stations that allow real-time analysis of mission systems during flight.

Command and Control

One of the F-35’s multi-mission capabilities in which the pilot can share data with allies in the air, at sea or on the ground to plan and execute missions.

CTOL - Conventional Takeoff and Landing

The F-35A variant is also referred to as the F-35 CTOL.

CV - Carrier Variant

The F-35C variant is also referred to as the F-35 CV.

DAS - Distributed Aperture System

The avionics system developed by Northrop Grumman that provides key capabilities, such as missile warning, navigation, search, and track that increase the pilot’s situational awareness.

EOTS - Electro-optical Targeting System

The avionics system that performs air-to-air and air-to-surface targeting, high resolution images, and tracking on the F-35.

Flight Test

The process of flying aircraft to collect, analyze and evaluate data for verification of flight characteristics, safety requirements, and the validation of design specifications.

Foreign Military Sales

The government-to-government process by which the U.S. sells F-35s to non-partner nations.

HMD - Helmet-mounted Display

The system that projects symbology on to the pilot’s visor that provides information typically on a heads-up display no matter which direction the pilot is looking.

Industrial Participation

The international F-35 supplier network based on building global, best-value partnerships among industries, partner nations and other international customers.

ISR - Intelligence, Surveillance and Reconnaissance

One of the F-35’s multi-mission capabilities in which the pilot can actively or passively gather data and photos of enemy operations.

JAST - Joint Advanced Strike Technology

Program that became the F-35 Joint Strike Fighter Program. Its original goals were maturing technologies, developing requirements and demonstrating concepts for affordable, next-generation joint strike fighter warfare.

JPO - Joint Program Office

The program management team consisting of U.S. Air Force, Navy and Marine Corps personnel, made up of integrated product teams responsible for F-35 systems, tests, operations and functional support.

JSF - Joint Strike Fighter

The name given to the program when it moved into the Concept Definition Phase, representing the requirement to produce aircraft with common components for the Air Force, Marine Corps and Navy.

LRIP - Low Rate Initial Production

The F-35 program phase that includes ramping up manufacturing of production jets.

Mission Systems

Also known as avionics, the integrated electronic sensors, displays and communications systems that collect and share data with the pilot and allies in other aircraft, at sea and on the ground.

Multirole Fighter

A fighter aircraft designed to excel in multiple combat missions. The F-35's roles include air-to-air; air-to-ground; intelligence, surveillance and reconnaissance; electronic attack; and command and control.

PBL - Performance Based Logistics

A sustainment approach where a contractor provides product support to maintain customer-defined readiness levels.

SDD - System Development and Demonstration

The F-35 program phase that includes manufacturing and testing 19 aircraft - 13 flight test and six ground test F-35s.

Stealth

The ability to evade detection by radar, infrared sensors or emission interception.

STOVL - Short Takeoff And Vertical Landing

The F-35B variant is also referred to as the F-35 STOVL.

Supersonic

The speed of travel that exceeds the speed of sound, which is considered to be Mach 1.

Sustainment

The process of maintaining aircraft readiness with logistics, maintenance and fleet data.

Probe-and-drogue

A method of aerial refueling where a probe from the receiving aircraft fits into a trailing hose with drogue attachment from a tanker aircraft.
