In 1959 there were some conceptual work done in the Polish air force with respect to the in-flight refuelling. Three schemes were taken into consideration:

Scheme A - Lim-2 (licence-built MiG-15bis) or Lim-5 (licence-built MiG-17F) as a tanker and Lim-5 as a receiver. The drouge of the tanker would be installed in the port underwing tank.

Scheme B - Lim-2 or Lim-5 as a tanker and Lim-5 as a receiver. The drogue would be installed under the tanker's belly (fuel would be transferred from the tanker's main tank).

Scheme C - Il-28 as a tanker and Lim-5 as a receiver. The drouge would be installed in the Il-28's bomb bay. The tanker would carry fuel for two fighters.

The design of instalation of a probe in the receiving Lim-5 was referred to as Scheme D.

During discussions in the air force's HQ Scheme C was considered the only worth further development. The project was however closed in the early 1960s.

Here you've got some original drawings as well as some contemporary visualisations of the concept.
