Foreign upgrades that surpass original aircraft

[Justo Miranda]

Theres also the spanish built version of the HE-111,the CASA_2.111 series.
This was a mixture of reengined and new builds using the RR Merlin engine and the nacelle developed for the beaufighter II and Lancaster.
Performance looks to have been comparable to its german engined predecessor and it even saw combat in the ifni war in 1957/58

Combat?

My father was stationed in Sidi Ifni when all this happened and he told me that the incident was a comedy staged by the Americans to prove that the Spanish Air Force F-86s were not really ours. Something similar to what they are trying to do now with Israel. The He 111 was already obsolete in 1940 and had a bad reputation among Spanish pilots who preferred the Ju 52 to fly from the Canary Islands to Ifni.

Why has no country that used F4 Phantoms ever created their own electronic warfare G version?

The F-4G was a specialized air-defence destroyer aircraft, not an electronic warfare aircraft.

Only the MiG-21-2000 variant, named "Lancer", was actually put into service.
Upgrading the MiG-29 was too expensive for Romania, so they concentrated on upgrading the MiG-21M & MF "Lancer".

In fact the Mig-21-2000 was a concept demonstrator developed by the israeli IAI firm in order to atract customers.
