The '''F-4EJ Kai (F-4EJ改)''' was a crucial upgrade for the {{Annotation|JASDF|Japan Air Self-Defense Force}} to extend the operational life and enhance the combat capabilities of its domestically produced [[F-4EJ|F-4EJ Phantom IIs]], which were becoming outdated by the early 1980s. Initiated under the Aircraft Structural Integrity Program (ASIP), the modernisation effort began in 1980, with development taking place between 1981 and 1982, leading to its first flight in 1984. This upgrade introduced advanced radar and {{Annotation|FCS|Fire Control System}}, improved navigation and communication capabilities, and integrated modern missiles and bombing systems. A total of 90 F-4EJ Phantoms were converted to the F-4EJ Kai standard, enabling them to serve for an additional three decades until their decommissioning in 2021, with the last unit retiring under the [[F-4EJ ADTW|Air Development and Test Wing (ADTW)]].

The '''F-4EJ Kai''' was introduced in [[Update "Direct Hit"]]. While it retains the classic [[F-4 Phantom II (Family)|F-4 "Phantom II"]] fuselage, it has been upgraded with 1990s technology to keep it relevant in modern combat. Notably, it shares the same PD radar, RWR, and weapon suite as the [[F-16 (Family)|F-16A "Fighting Falcon"]], making it a formidable opponent. To maximise its effectiveness, pilots should focus on using the AIM-7Fs for long-range engagements and head-on attacks while relying on the AIM-9Ls for quick kills in dogfights. However, it's crucial not to linger in close-quarters combat for too long, as more manoeuvrable jets can quickly gain the upper hand. Fire the missiles, secure the kill, and reposition before another opponent can sweep in. A more risky strategy involves intentionally slowing down the heavier F-4E airframe by making tight turns and using airbrakes, which can cause pursuing aircraft to overshoot. By flaring off incoming IR missiles and forcing the enemy into an overshoot, the F-4EJ Kai can get on the opponent's six, allowing it to finish them off with either an AIM-9 or a precisely calculated gun burst using its ballistic computer. This tactic, while dangerous, can turn the tables on unsuspecting adversaries who underestimate the F-4 by overestimating their own speed and missile capabilities.

The F-4EJ Kai is the ultimate Japanese package of the [[F-4 Phantom II (Family)|F-4 "Phantom II"]]. Equipped with the same pulse-Doppler radar as on the [[F-16 (Family)|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 [[F-4 Phantom II (Family)|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.

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], [[F-4EJ ADTW|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. <ref>https://theaviationist.com/2021/03/17/japans-last-three-f-4ej-phantoms-have-just-flown-for-the-last-time/</ref>

Description

The F-4EJ Kai (F-4EJ改) was a crucial upgrade for the JASDF to extend the operational life and enhance the combat capabilities of its domestically produced F-4EJ Phantom IIs, which were becoming outdated by the early 1980s. Initiated under the Aircraft Structural Integrity Program (ASIP), the modernisation effort began in 1980, with development taking place between 1981 and 1982, leading to its first flight in 1984. This upgrade introduced advanced radar and FCS, improved navigation and communication capabilities, and integrated modern missiles and bombing systems. A total of 90 F-4EJ Phantoms were converted to the F-4EJ Kai standard, enabling them to serve for an additional three decades until their decommissioning in 2021, with the last unit retiring under the Air Development and Test Wing (ADTW).

The F-4EJ Kai was introduced in Update "Direct Hit". While it retains the classic F-4 "Phantom II" fuselage, it has been upgraded with 1990s technology to keep it relevant in modern combat. Notably, it shares the same PD radar, RWR, and weapon suite as the F-16A "Fighting Falcon", making it a formidable opponent. To maximise its effectiveness, pilots should focus on using the AIM-7Fs for long-range engagements and head-on attacks while relying on the AIM-9Ls for quick kills in dogfights. However, it's crucial not to linger in close-quarters combat for too long, as more manoeuvrable jets can quickly gain the upper hand. Fire the missiles, secure the kill, and reposition before another opponent can sweep in. A more risky strategy involves intentionally slowing down the heavier F-4E airframe by making tight turns and using airbrakes, which can cause pursuing aircraft to overshoot. By flaring off incoming IR missiles and forcing the enemy into an overshoot, the F-4EJ Kai can get on the opponent's six, allowing it to finish them off with either an AIM-9 or a precisely calculated gun burst using its ballistic computer. This tactic, while dangerous, can turn the tables on unsuspecting adversaries who underestimate the F-4 by overestimating their own speed and missile capabilities.

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:

  • Improved over the F-4EJ with better stock modifications.
    • Starts with 2 x AIM-9Ps and 2 x AIM-7Fs instead of AIM-9Bs.
    • Unlocks 4 x AIM-9Ps at Tier I without needing AIM-9Es.
  • Versatile armament options for various playstyles.
    • AIM-7F missiles offer long range, excellent manoeuvrability, and high G tolerance.
    • AIM-9L missiles provide superior manoeuvrability, medium-long range, all-aspect tracking, and decent rear-aspect flare resistance.
    • Can carry up to 8 missiles (4 IR, 4 SARH).
  • Ballistic computer aids in aiming cannons, rockets, and bombs.
  • Large supply of countermeasures.
  • AN/APG-66 radar with advanced scanning, tracking modes, and strong resistance to notching and chaff.
  • Advanced cockpit HUD for easy target tracking in simulator mode.

Cons:

  • Limited ammunition for the frontal cannon.
    • Carrying additional gun pod(s) weigh down the plane considerably.
  • No guided ordnance, reducing ground attack effectiveness.
  • Poor manoeuvrability and average acceleration/top speed, especially compared to typical opponents.
    • Lacks the Agile Eagle package (F-4E / F-4F), which would enhance maneuverability.

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]
