I thought that the addition of heavy lift CC-154 Bison would be useful to my AU Royal Hellenic Air Force, so here is my version and the back up history:
In late mid 1990's Hellenic Kingdom wanted a heavy lift aircraft for supporting peacekeeping missions, also own emergency assist missions aboard and heavy/bulky loads to Cyprus. Only two choices were available, used Il-76 from Russia or the used CC-154 Bison which were offered for sale. In total 14 ex-RCAF aircraft were purchased in 1998-1999, since Hellas preferred a western aircraft instead of a Soviet/Russian. The Five Year Defense Plan of 2005-2009 included a full rebuilt of old Bison to C.3 spec. A new squadron was formed for them (373th Heavy Transport Squadron), which operates 12 aircraft painted as below and 2 given to Hellenic Center for Polar Research, but still maintained by RHAF staff.
The Bison supplement the 24 Lockheed C-130 of RHAF (18 C-130H/6 C-130H-30), which were also rebuilt to -J spec, since Hellenic Aerospace Industry participates to Super Hercules program from its beginning. All C-130J(H)/C-130J(H)-30 belong to 356th Tactical Transport Squadron.
Although Bisons belong to 112th Air Wing of Elefsis, their base is Larisa Airfield together with the MD-11C(K) and VC-10K of 372th Air Refueling Squadron because this airfield is one of largest military airfields in Balkans in my scenario.
P.S I think that KIKE92 would like my idea of a Hellenic Bison.
