Raketa (Russian: Раке́та, Rocket) was the first type of hydrofoil boats commercially produced in the Soviet Union. They were manufactured from 1957 until the early 1970s. The chief designer was Rostislav Alexeyev and the project 340 vessels had been planned already in the late 1940s.
The first model, Raketa-1, was built by Krasnoye Sormovo (Красное Сормово) shipbuilding plant in Sormovo, Nizhny Novgorod (Нижний Новгород). On its maiden voyage, on 25 August 1957, it carried 30 passengers from Nizhny Novgorod to Kazan (420 km) in seven hours.
Raketa boats were soon in wide commercial service on the Volga River and elsewhere in the Soviet Union. To this day, the name is often used generically in Russian for all hydrofoil river boats. Later designs include the Meteor and Kometa types, among many others.
There were several versions of project 340 vessels: project 340 (проект 340), project 340E (проект 340Э) and project 340ME (проект 340МЕ).
In Finland the traffic with project 340 vessel started in 1962, when the cities of Lahti and Jyväskylä had a joint-venture company, which bought one vessel. They prolonged the operations until 1983. After that the ownership was transferred to the private persons. The first name of the vessel was Tehi due to the one part of the southetnmost Päijänne, Vesijärvi. Later the hydrofoils were taken off. Later M/S Tehi became M/S Suvi-Tuuli.
M/S Tehi started its operations in 1962. Later the M/S Tehi was renamed as M/S Suvi-Tuuli (without hydrofoils):Lake Päijänne cities of Lahti and Jyväskylä 1962-1983, Pyhäjärvi 2008, river Kokemäenjoki 2009-
