Greek Tjeld-type patrol boat

The Greek Tjeld type patrol boats were a set of six fast patrol boats built to a Norwegian design and operated by the Hellenic Navy during the 1960s and early 1970s.

Construction
The six vessels were built by the Norwegian company Westermoen of Mandal, Norway, to the same design as that of the Tjeld class patrol boats built by Westermoen for the Royal Norwegian Navy in 1959. This was in turn based on their prototype fast patrol boat, the Nasty, and the Greek vessels are also described as the “Improved Nasty type”. Other sources give the names “Nasty-type” and “Nasty-class” patrol boats.

The vessels were ordered in 1965, identical to the Tjeld boats except they had two 40mm guns instead of the single 40mm and 20mm guns of the Tjeld boats. They were delivered in 1967, and commissioned with astronomical names. They were the first warships built for the Greek navy since the 1930s.

Service history
The six vessels remained in service until the 1980s. In 1982 Iniohos was discarded and the remaining vessels were re-numbered P196-200 (inclusive); all were decommissioned and placed in reserve or sold in 1983. In 1989 four boats were re-engined and re-activated, but by 1985 all had been disposed of.
