Maybe Brazil is just buttering up the UK for a deal on one of the QE carriers, the cash would be welcomed for covering expenses on Tempest and Dreadnought development.
Now, now ...!
#1 - The UK will not be selling the carriers , well not at least for the next 25 years !.
Let's put things into perspective. In the early 2010's Brazil was in talks to purchase LOTS of things from the UK & others (with regards military equipment / hardware) purchasing things like OPV's & submarines. As one of the richest South American countries, her coffers were full & the cash was burning a hole in their pockets. Various issues around corruption & political turmoil, caused a change in government, which in turn slowed things down, along with COVID.
Following the recent re-election of the previous president, there has been a slow up turn in activities. Like many 2nd tier military nations, the prospect of having your own indigenous manufacturing facilities to produce items locally, is an appealing option & it wouldn't surprise me if other defence elements come out from behind closed doors in the remainder of 2025 / 2026.
In the meantime, replacing an ageing fleet of naval equipment from the 2nd hand market place, also make some financial sense (due to maintenance / operability & upkeep costs). Purchasing ALBION & BULWARK, is a complimentary buy to match a previous purchase, in the form of HMS OCEAN. Commonality of systems & equipment across their fleet & with 'close neighbours' (such a Chile), will help provide more stability within the continent.
