In 1968 RHN received also about 20 QH-50C DASH for use in Gearing FRAM I destroyers. Flied and maintained by experienced members of the ships' complement, RHN achieved availability of its DASH unheard even to JMSDF and continued to use it until well into the 1970's. RHN used the DASH in other missions as well with ASW, such as fire support, smoke generator, reconnaissance and EW- ironically all tested by USN in 1960's. The long service history of the DASH in RHN and the experience gained led to the SHAF HC-50, which developed to eliminate the two main drawbacks of the helicopter. First, everything was exposed, so when flying in low altitude above sea salt covered everything and therefore a very careful washing was needed when returned back to the ship. Secondly, the drag was large and the airborne time was limited. So, a specially designed aluminium/fiberglass cover was developed from SHAF and tested with great success in late 1970's, while the helicopter was fully reversed engineered from SHAF during the 1980's. Another 36 HC-50 built and the helicopter find its way to Hellenic Army, Frontier Guard and in some Security Forces, using a modified Pegasus ground Station as well. Capable of lifting 400kg, the HC-50 can also provide critical items in snow-blocked villages during winter in Northern Kingdom, when the ATV Perseus cannot reach.
In the nose the indigenous Ligeas Mk3 EO/FLIR system can be placed from 1987, meaning that its fire support missions could be expanded more, providing much better weapon targeting from the old TV-guidance/targeting system. The Ligeas together with the Polyphemus Laser Guidance Pod created a very stable UCAV platform with double duration from the original DASH, thanks to aerodynamic shape and much improved engine, each system is used with certain weapons or in reconnaissance missions.
Last HC-50 built were civilian versions, for use by the State Electric Company (Network surveillance/monitoring possible damages etc) and Ministry of Environment (measuring with various equipment, taking samples for research in Ministry laboratory etc). An unarmed Ligeas HC-50 variant is used from the Forestry Guard and Police Forces. Note that Ministry is the only HC-50 user without ground station but has only the convectional modified multi channel radio control system (which is back-up guidance in other HC-50).
Finally the HC-60 is a completely new airframe first revealed in 2008. It features a new recovering system developed with french assistance (something similar with the SADA), providing landing about 4 times more accurate than the old ACCRLS (Automatic Computer Controlled Remote Landing System) of the HC-50. This means that RHN started to phase out the venerable HC-50, process which will be completed until 2016. The HC-60 entered service in 2012 and tested also with ASM-12 missiles (HC-50 can carry only rockets), has increased load capacity due to the lighter purpose developed turboshaft engine, a much more efficient unit than the obsolete 1950's Boeing derived turboshaft of the HC-50. Speed and duration is also increased. Cyprus shown great interest from the beginning of the HC-60 program and ordered 16 units of which 6 are already in service with Navy Command. Land Command will follow in near future, while 2 of Cypriot HC-60's are in service with the Marine Police. RHN order is for 20 airframes, Army and Security Forces will also follow within the decade.
In HC-50 variants first 4 are in service with RHN and follow : Frontier Guard, Army, Forestry Guard, Gendarme, State Police and finally State Electric Company and Ministry of Enviroment.
Note that Frontier Guard has also some green HC-50 like Army version and the HC-60 timeline includes also weapons testing.
P.S The QH-50 DASH included above is an improvement of that found in old parts sheets.
