HMAS Melbourne '84

In this timeline, rising regional tensions, new Indo-Pacific threats and failure to secure a new carrier during the late 1970s drove Australia to cancel Melbourne's planned retirement. Instead, an ambitious and full modernization was authorised, with plans finalised by 1980 and taking place between 1981-1983.

• Two Phalanx CIWS replaced a pair of her aging twin 40mm Bofors mounts for close-in defense, a pair of M2HB Browning heavy machine gun postions take the place of the remaining twin 40mm Bofors mounts for defence against asymmetric threats and the single Bofors mounts were updated with electrically powered mounts and retained to defend against helicopters, slow/low flying aircraft and small fast attack craft.
  
  
• Upgraded radars, communications, and electronic systems were installed. Flight deck was overhauled, steam catapult and arresting gear refurbished and the hangar was reconfigured to support up to 26 aircraft for fleet air defence, strike, ASW, AEW, and utility operations. Propulsion and auxiliary systems received overhauls to extend her operational life by up to another 15 years.

Recommissioned in late 1983, this kitbash is as I think she could have appeared by 1984 ready to serve out a few more tours of duty through the remainder of the Cold War and the edge of the 20th century.

The close in weapons have been revised, many changes are enhancements to the weapons load outs of the air wing, mostly the Skyhawk (see further info below) and a few systems updates to radar which are now represented visually in the mod as off the last update. I have come up with a bit of headcanon in the ship's description, but I leave her to you to come up with your own scenarios.

• 12 × A-4AU Super Skyhawk (Strike Fighter — upgraded radar, Sidewinder air-to-air missiles, Maverick capability) - see below for more details
  
  
• 6 × S-2G Tracker Mk.2 (ASW and maritime patrol - minor upgrade to be able to equip 2 x Harpoon AShM and a heavy ASW Killer loadout)
  
  
• 4 × Sea King Mk.50A (ASW helicopter - can perform SAR minigame)
  
  
• 2 × Sea King Mk.50A AEW.2A (Airborne Early Warning)
  
  
• 2 × Wessex HAS.31B (SAR and light utility - updated to be able to perform the new SAR minigame. They still have their ASW weapons if you wish to use as a backup)

In this alternate history, the Commonwealth Aircraft Corporation (CAC) was given new life and partnered with Douglas to refurbish surviving A-4G airframes and license-build new airframes for the RAN. The resulting Super Skyhawk (A-4AU being the unique Australian designation) featured an upgraded lightweight pulse-doppler radar derived from the AN/APG-66 radar, avionics, expanded weapons compatibility (AIM-9L Sidewinders, Mavericks, Rockeyes, Shrikes and Harpoon anti-ship missiles), and a more powerful J52-P-408 turbojet engine for better range and reliability — ensuring Melbourne’s strike capability into the 1990s.
I have tried to keep the loadouts relative to the aircraft's size. This concept is inspired by real life upgrades to the Skyhawk like the A-4K Kahu and similar upgraded Skyhawks.

✅ Realistic alternate-history air wing
✅ Balanced for late Cold War-era scenarios
✅ Designed for Pacific, Indian Ocean and Gulf settings
✅ Strong commonwealth theme — ideal for players looking to explore a "what if" Australian naval resurgence

Defend the Commonwealth. Patrol the Pacific. Rewrite history.

Please let me know of any issues! This is my first mod so I may have overlooked something, I have tested dozens of times so should be all good.
