Lentorykmentti 4 (Flying Regiment 4) was formed from Lentoasema 6  (Flying Station 6) on 1 January 1938. The regiment operated well into the post-war period, until all flying regiments were disbanded on 1 December 1952 and most of them formed into air commands (lennosto). Lentorykmentti 4 became the new 1. Lennosto, which was renamed Hämeen Lennosto at the beginning of 1957 and Lapin Lennosto on 6 December 1974. It continues to operate by that name to this day.

Lentorykmentti 4 was the Finnish bomber flying regiment.
