90 Days After 9/11: "Largest Military Procurement in History"

Blogger note: This post rests for its relevance on the theory that most big moves in the defense, intelligence, and aerospace industries soon after and prior to September 11, 2001 are probably significant, albeit sometimes indirectly:

Green Hills Software's INTEGRITY® Selected As Operating System For F-35 Joint Strike Fighter

Green Hills to Provide Operating System and Development Environment for Largest Military Procurement in History

Santa Barbara, CA, October 31, 2001 -- Green Hills Software, Inc., today announced that Lockheed Martin will be using Green Hills' INTEGRITY® real-time operating system (RTOS) and AdaMULTI® 2000 software development tools to develop software for its Joint Strike Fighter (JSF) aircraft. Lockheed Martin's design for the JSF was selected by the Department of Defense (DoD) in a $200 billion award, the largest in US DoD history. Avionics software developed by Lockheed Martin will run on airborne PowerPC processors operating under the INTEGRITY RTOS.

F-35 Joint Strike Fighter "We're proud to be part of the Lockheed Martin JSF team," said John Carbone, vice president of marketing at Green Hills. "Lockheed Martin's selection demonstrates INTEGRITY's ability to meet the demanding security and safety-critical software requirements of the Joint Strike Fighter. This design win demonstrates our commitment to the airborne computer marketplace."

Carbone continues, "The INTEGRITY RTOS, together with Green Hills' AdaMULTI IDE, and Ada 95/C/C++ compilers provides a complete single-vendor RTOS and development solution for developing real-time mission and safety-critical software systems capable of meeting the security and safety standards of ISO/IEC 15408 (Common Criteria) and RTCA DO-178B. No other RTOS provides a more secure, memory-protected run-time system capable of meeting the security and safety requirements of today's advanced avionics and flight control systems."

John Ledyard, software manager at Lockheed Martin adds, "INTEGRITY is an outstanding product that we are very excited about. Green Hills involved us early in product definition and as a result INTEGRITY meets our needs. An embedded RTOS with virtual memory support and the capability to meet security standards was a key enabler in the design of our mission critical software. In the past, we would have to develop a custom RTOS and modify development tools at a significant cost. With INTEGRITY, and its tight integration with the excellent AdaMULTI software development tools, we are able to focus our efforts on our strengths which are in application software development and integration. This will result in reduced cost and risk for us and our customers."

INTEGRITY RTOS is optimized for safety-critical embedded applications that place a premium on maximum reliability, security, and testability. It features advanced memory protection capabilities, an optional ARINC-653 partition scheduler, dynamic download, task- and system-level debug, a configurable real-time EventAnalyzer, POSIX support, and TCP/IP networking. It is also the first memory-protected real-time operating system to be offered on a royalty-free basis.

INTEGRITY is engineered from the ground up to provide security and determinism. At the lowest level, the kernel employs an object-oriented design and access verification to protect against inadvertent and malicious kernel access problems such as invalid kernel addresses and invalid system call parameters. The kernel design also guarantees bounded computation times by eliminating the need for features such as dynamic memory allocation and heuristic scheduling. Underlying hardware mechanisms are used to provide full system memory protection of all components, including user applications, device drivers, and inter-address space communications. Clocks and timers are protected with access permissions and implemented entirely in software.

INTEGRITY is tightly integrated with Green Hills' AdaMULTI® IDE. Together with Green Hills' family of optimizing Ada 95, C, and C++ compilers, AdaMULTI automates all aspects of embedded software development, including editing, source-level debugging, program building, run-time error checking, version control, and code/performance optimization. INTEGRITY also features ISIM, an RTOS simulator that enables programmers to develop and test their code on a PC or workstation without the need for target hardware. INTEGRITY also includes the EventAnalyzer, which enables viewing of system and user events in a graphical display.

Lockheed Martin is headquartered in Bethesda, Md., and is a global enterprise principally engaged in the research, design, development, manufacture and integration of advanced-technology systems, products and services. The corporation's core businesses are systems integration, space, aeronautics and technology services.

Joint Strike Fighter (JSF)

The F-35 is the result of the Defense Department's Joint Strike Fighter (JSF) program, which sought to build a multirole fighter optimized for the air-to-ground role with secondary air-to-air capability. The JSF requirement was to meet the needs of the Air Force, Navy, Marine Corps and allies, with improved survivability, precision engagement capability, and reduced life cycle costs. By using many of the same technologies developed for the F-22, the F-35 has the opportunity to capitalize on commonality and modularity to maximize affordability.

The Lockheed Martin X-35 was chosen over the competing Boeing X-32 primarily because of Lockheed's lift-fan STOVL design, which proved superior to the Boeing vectored-thrust approach. The lift fan, which is powered by the aircraft engine via a clutched driveshaft, was technically challenging but DoD concluded that Lockheed has the technology in hand. The lift fan has significant excess power which could be critical given the weight gain that all fighter aircraft experience.

Lockheed Martin developed four versions of the Joint Strike Fighter to fulfill the needs of the Navy, Marine Corps, Army, Air Force and the United Kingdom Royal Air Force and Navy. All versions have the same fuselage and internal weapons bay, common outer mold lines with similar structural geometries, identical wing sweeps, and comparable tail shapes. The weapons are stored in two parallel bays located aft of the main landing gear. The canopy, radar, ejection system, subsystems, and avionics are all common among all different version as is the core engine which is based on the F119 by Pratt & Whitney.

Additional systems on the F-35 include:
  1. Northrup Grumman advanced electronically scanned array (AESA) multi-function radar
  2. Snader/Litton Amecon electronic countermeasures equipment
  3. Lockheed Martin electro-optical targeting system
  4. Northrup Grumman distributed aperture infrared sensor (DAIRS) thermal imaging system
  5. Vision Systems International advanced helmet-mounted display

F-35 Variants:

US Air Force

The Air Force expects that to purchase 1763 F-35s to complement the F-22 Raptor and replace the F-16 as an air-toground strike aircraft. The Air Force variant includes an internal gun, infrared sensors, and laser designator. This is the technologically simplest version of the JSF, in that it does not require hover or aircraft carrier capability. Therefore it does not require the vertical thrust or the handling qualities for catapult launches, augmented control authority at landing approach speeds and strengthened structure to handle arrested landings. At the same time, the Air Force F-35 will have to improve upon the high standards created by the F-16. Since replacement of the F-16 by the F-35 will entail a significant payload reduction, the F-35 faces a very demanding one shot one kill requirement.

US Navy

The requirement for carrier operations creates the largest differences between the Air Force and Navy version. The naval version has larger wing and tail control surfaces to enable low-speed approaches to aircraft carriers. Leadingedge flaps and foldable wing tip sections account for this increased wing area. The larger wing area also provides the Navy version with an increased payload capability. To support the stresses of carrier landings and catapult launches, the internal structure of this version is strengthened. In addition, the landing gear has longer stroke and higher load capacity, and of course an arresting hook is added. Compared to the F-18C, the F-35 has twice the range on internal fuel.. The design is also optimized for survivability, which is a key Navy requirement. Like the USAF version, the Navy version will incorporate an internal gun and sensors. This new fighter will be used by the Navy as a first-day-of-war attack fighter in conjunction with the F/A-18 Hornet. The Navy plans to purchase 480 JSF.

US Marine Corps

The distinguishing feature of the USMC version of the JSF is its short takeoff/vertical landing capability (STOVL). There will not be an internally mounted machine gun, but an external gun can be fitted. This version requires controllability on all axes while hovering. Another critical design feature is its impact on the ground surface beneath it during hover. The USMC expects their version of the JSF will replace the F/A-18 Hornet and the AV-8 Harrier. The Marine Corps expects to purchase 480 STOVL versions of the F-35.

United Kingdom Royal Navy and Air Force

This version will be very similar to the one procured by the United States Marine Corps.
