The first four batches of modernised F-15EX Eagle II fighters will remain without external fuel tanks but will be able to carry more missiles

Boeing is nearing delivery of the first F-15EX Eagle II fighter in its final configuration. It, and several dozen other aircraft, will not have conformal fuel tanks.

Here's What We Know

The F-15EX is a modernised version of the F-15 airframe that appeared almost 50 years ago. Along with the new EPAWSS (Eagle Passive Active Warning Survivability System) electronic warfare system, one of the innovations is the presence of conformal fuel tanks.

However, the fighters of the first four batches will not have them. Under Lot 1-4, the U.S. Air Force will purchase 54 production fourth-generation fighters. Two test aircraft already in service have fuel tanks.

The F-15EX Eagle II version without additional tanks will be able to carry up to 12 missiles, but will have a limited range. Therefore, these aircraft will be used primarily for air-to-air operations.

The U.S. Air Force is now seeking funding for 12 sets of conformal fuel tanks for the fifth batch of F-15EX Eagle IIs for fiscal year 2024. In addition, the military service has asked Congress for funding to purchase 12 more kits for the same batch.

Thus, if approved, all 24 aircraft in the fifth batch will be equipped with conformal fuel tanks. They will accommodate more than 4,000kg of fuel. It is important to note that the Lot 5 deal has not yet been finalised.
