Description

The F-4EJ Kai Phantom II (known as F-4EJ改) was one of the cornerstone of the JASDF based on previous F-4EJs manufactured in Japan; as the airframe and avionics started to become obsolete by early 1980s, MHI and JASDF planned for the upgrades for the fleet of Phantoms with new controls, navigation systems and pulse-doppler radar. After the budget was passed, 90 of these jets were then converted into F-4EJ Kai standards and served JASDF for the next 3 decades until their ultimate decommission in 2021 from ADTW of JASDF.

Introduced in Update "Direct Hit" as one of the earliest jets to receive PD radar in future updates, F-4EJ Kai introduced enhanced avionics for the already obsolete airframe of F-4EJ while retaining its combat capabilities against future jets or bombarding enemy ground target with high bomb payload. But be sure plan ahead for any assaults and avoid dogfights with other jets since hit-and-run greatly enhance the survivability of the jet.

Usage in battles

The F-4EJ Kai is the ultimate Japanese package of the F-4 "Phantom II". Equipped with the same pulse-Doppler radar as on the F-16 "Fighting Falcon", the EJ Kai possesses the ability to use a fantastic radar for its airframe, battle rating, and missile arsenal to employ it in the best possible way, allowing it to quickly lock targets for AIM-9Ls and AIM-7Fs which can guarantee aerial kills above ~20 m ground clearance.

While the radar and cockpit avionics get a whole upgrade package (which greatly enhances its simulator capabilities due to its cockpit HUD), the airframe is still a Phantom II after all, lacking any real manoeuvrability without access to the "Agile Eagle" modification found on the American F-4E Phantom II. The F-4EJ Kai is, ultimately, a missile bus which hits hard.

As with all Phantom IIs, the EJ Kai is a multi-role fighter with the capability to carry plenty of rockets, gun pods and bombs. However, due to it serving under the Japanese JASDF and its defensive doctrine, it lacks GBUs, AGMs, or Napalm bombs found on other (late) model Phantoms. While it is certainly possible to go multi-role, due to its large amount of carry capacity, it will turn its missile bus experience into a freight train towards bases or ground targets. This is only advised for quick carpet passes in ground battles or when trying to unlock later modules in air battles with priority towards AAMs, as the enemies facing the F-4EJ Kai won't have any issues intercepting a loaded Phantom.

Pros and cons

Pros:

  • Eased up modifications over the F-4EJ
    • Comes with 2 x AIM-9Ps stock instead of 2 x AIM-9Bs
    • 4 x AIM-9Ps is a tier I mod without the need of AIM-9Es
  • A wide range of suspended armaments, suitable for any playstyle
    • Powerful AIM-7F SARH missiles, with very long range, manoeuvres straight off the rails and have 25G of max overload
    • Top-of-the-line AIM-9L missiles, having excellent manoeuvrability of 30G, long-range, great all-aspect tracking, and being pretty flare resistant when firing rear-aspect
    • Can carry 8 missiles in total
  • Deadly frontal armament with high burst mass
  • Makes use of a ballistic computer to assist in the aim of cannons, rockets, and bombs against ground targets
  • Large reserve of countermeasures
  • AN/APG-66 radar - has diverse scan and tracking modes, very high resistance to notching and chaff, very long-range

Cons:

  • Limited ammunition in the frontally-mounted cannon
  • Lacks guided ordnance, limiting ground attack ability
  • Terrible manoeuvrability along with mediocre acceleration and top speed, particularly compared to common opponents
    • Doesn't have an Agile Eagle package like the F-4E and F-4F to increase manoeuvrability

History

Since the introduction of the Mitsubishi F-4EJ in 1968, it had been one of the cornerstones of the JASDF along with the F-104J and then later F-15J/DJ; but being a jet from the mid-1960s with inferior avionics and armaments to the latest Soviet jets also meant an extensive upgrade for the fleet of EJs was required. The plans for upgrading the 90 MHI-built F-4EJs which were still airworthy started in 1981 and the first retrofitted jet (07-8431) took to the skies in July 1984 and joined the JASDF in December. Upgrades included:

  • Installation of J/AYK-1 guidance system for AShM and unguided bombs
  • Replacing AN/APQ-120 with the latest AN/APG-66J with pulse-Doppler capabilities; J/AVQ-3 radar display and guidance system for SARH AAMs
  • New J/ASN-4 digital INS navigation system
  • New Kaiser Electronics HUD
  • J/APR-6 RWR, AN/APX-76A IFF, and AN/ALQ-131 countermeasures
  • HOTAS controls
  • Lightning rods by the radome
  • New fuel tanks

These features passed for the budgets of FY1987 and the upgrades for these jets finished by 1990.

By the time F-15J/DJs and F-2s joined the JASDF in larger quantities, F-4EJs (including the recon variant, RF-4EJ) were starting to retire. On 17 March, 2021, the very last 3 F-4EJ (Kai)s of the JASDF (17-8301[4038], 47-8336[M036] and 07-8431[M131]) retired from the Air Development and Test Wing (ADTW) in Gifu Airbase, Nagoya, bidding farewell of Phantoms in JASDF service. [1]

Msg-info.png 07-8431 (EJ Kai) and 17-8301 (the very first JASDF EJ) were also used for the sampling of the in-game representation of this jet as the developers and DMM announced for a trip to Gifu before their ultimate decommission.[2]
