Long-range, multi-target high resolution radar, precision air-to-surface and air-to-ground air-launched weapons, advanced EW and a variant of the fastest computer ever put in a fighter jet … are all key elements of a massive Japanese Super Interceptor Program designed to substantially modernize and enhance 68 of the Japanese Air Defense Forces F-15J fighter jets. The program aims to be completed by 2030.
The Japanese aircraft, to be worked on at Boeing’s St. Louis, Mo., facility through a DoD Foreign Military Sales contract with Japan, will receive paradigm-changing new technologies, many of which have already been integrated into the US Air Force’s F-15 EX.
New Weapons for JSI F-15
The technological upgrades are wide ranging and quite significant, according to an interesting essay in the Aviationist, as they include a comprehensive suite of technologies. A critical part of the upgrades includes a weapons envelope expansion and new forms of air-to-surface attack with the addition of the US-built AGM-158 Joint Air-to-Surface-Standoff Missile-Extended Range (JASSM ER).
This not only introduces land-attack possibilities but also extends attack range for the Japanese aircraft, which are intended to focus as supportive air-combat platforms to the F-35 by operating as a cruise missile carrier and supplemental attack platform. This makes great tactical sense, as Japan is acquiring a large force of F-35s and 5th-gen aircraft are intended to use stealth and speed to destroy enemy air defenses to open up an attack “corridor” for more heavily armed 4th-generation fighters. This synergy has been greatly improved in recent years by the US Air Force, which has found new ways to achieve two-way data link networking between 5th-and-4th generation fighter jets.
HIgh-Tech Computing
Japan is likely doing this as well, as evidenced by some of the other ongoing electronic, computing and communications upgrades fundamental to JSI. These include the addition of AESA Actively Scanned Electronic Array radar and AN/ALQ-250 EPAWSS Eagle Passive Active Warning Survivability System. AESA radar is well known as a next-generation threat detection system capable of scanning multiple targets simultaneously at longer-ranges on a wide range of frequencies using high-fidelity imaging.
The JSI F-15s are also getting Honeywell’s high-speed ADCP II Advanced Display Core Processor II. This computer, described as the fastest computer processing ever integrated into a fighter jet, has been added to the US Air Force’s upgraded F-15 Eagle II. Boeing developers told Warrior a few years ago that this ADCP computer performs 87 billion functions per second. The new processing speed not only supports improved air-attack weapons such as the AIM-9X or AIM-120 missiles, but can also enable continued software upgrades. Several years ago, former Air Force senior commander Gen. Arnold Bunch, explained this to Warrior in an interesting interview.
“If I do not put in the new computer with its throughput and processing power, there are certain apps I cannot run to grow and evolve it for the future,” Lt. Gen. Arnold Bunch, Jr. told me (Warrior) several years ago when he was the Military Deputy, Office of the Assistant Secretary of the Air Force for Acquisition. Bunch is now retired but also went on to serve as the Commander of Air Force Materiel Command as well.
