The International Fighter Conference took place in Rome, where discussions centered around the development of the sixth-generation fighter, known as the GCAP (Global Combat Air Programme), which is a collaborative effort among the UK, Japan, and Italy.

**Key Features of the GCAP**
Group Captain Bill Sanders, a British defense ministry official, emphasized that the GCAP should incorporate a versatile weapons bay capable of accommodating diverse armaments. This feature is intended to ensure compatibility with munitions used by NATO and the United States.

**Strategic Necessities**
Sanders highlighted the importance of this flexibility in light of operational insights from ongoing conflicts, such as the situation in Ukraine, where the rapid depletion of munitions and increased pressure on supply chains necessitate a varied arsenal. He pointed out the critical need for commanders to have the ability to access a wide range of weaponry to enhance operational flexibility in combat scenarios.

**Cost Efficiency in Warfare**
The discussion also addressed the need for the GCAP to utilize expensive precision munitions initially, with a transition to more economical unguided bombs as defensive positions weaken. Sanders articulated the goal of optimizing the cost-per-kill ratio while effectively dismantling enemy defenses.

**Collaborative Combat Aircraft (CCA) Integration**
Sanders noted that the GCAP should also be compatible with various Collaborative Combat Aircraft (CCA), a feature deemed essential for operational readiness. He explained that the fighter needs to adapt to whichever drones it encounters.

**Independent Development Trends**
Military analyst Douglas Barrie remarked that it is logical for the UK, Japan, and Italy to develop their own unique CCAs to maintain sovereign capabilities. He acknowledged the potential for collaboration in the future but indicated that independent development currently allows for greater choice and flexibility.

**Challenges in Adaptation**
At the conference, Turkish officials mentioned plans to match a CCA with the Eurofighter jets they recently agreed to purchase. In contrast, Jorge Tamarit-Degenhardt, CEO of Eurofighter, raised concerns over the costs associated with adapting fighters to integrate with multiple CCAs from different nations, emphasizing resource limitations.
