Are you sure it is possible to build a bigger carrier for 300 million Euros, I think that is now impossible and have my doubts that it can be done for less than 900 million and probably more. Consider the Cavour has not yet entered service and currently stands at 1.4 billion Euro although that is slightly larger than all of the above.

The budget aproved for the Strategic Projection Ship (27.000 T.) is 360 Million € nothing else.

Obviously the BPE is not an Aircraft Carrier as it. The spanish BPE is an LHD with Skyjump for the AV-8B+ and F-35B, with standard capacity of 10 AV-8B+/F-35B & 10-12 SH-3/NH-90. (Max. Capacity: 30 under deck + 6 operating over deck).

The BPE is not comparable to the italian Cavour, since he is an STOVL Aircraft Carrier with a minimal amphibious capacity, whereas the main roll of the BPE is the projección of spanish Marines and Army. For that reason its dock for 4 LCM-1E/LCM-8 & 6 RHIBs, the two garages for vehicles (up to 46 MTBs and a hundred of IFVs), its capacity for more than thousand troops, it four spots for Chinooks on the deck and one for the Osprey, if the tillrotor were ordered by Spain…
