以前からテンペストは当初のモックアップとは違う見た目になるであろうことをBAEのFCAS責任者が言ってる。
もともと公開されていない様々な形とサイズのコンフィギュレーションがあったので、それらの
検討の中で日本の要望も取り入れていっただけ。
早いうちにデザインを固定しない方式でテンペストの開発が進められていることは既出。

Although BAE produced full-scale models of a notional Tempest design, and displayed them
at airshows at Farnborough, Fairford, Cosford and Duxford, and despite multiple computer-
generated renderings and animations showing the same basic twin-finned, twin-engined
tailless Delta design, the FCAS core element could look very different indeed.

By the time most aircraft programmes become public knowledge, a configuration has been
chosen, and concept artwork usually bears a close resemblance to the eventual production
aircraft. Michael Christie, however, has already cautioned that the fighter that emerges from
the FCAS programme “may not look like the concept aircraft unveiled in 2018.”

When AIR International spoke with Michael Christie in March 2021, he said “we're still looking
at multiple options for the configuration of the core, manned, or optionally manned platform.
We're looking at the balance between the various components and at how best to distribute
capability across the overall system. We will model various different sizes and shapes and the
different capabilities and roles that each of the components carry out, trying to find the balance
between the most effective and the most affordable. So we will be keeping our options open for a while yet.”
