The specification of the modernization of the Slovak Air Force Mi‑17 helicopters was created in March 2001 and was formulated in the document "Tactical-Technical Assignment 'MODER Mi‑17' - Modernization of Mi‑17 helicopters of the Slovak Air Force". The state owned enterprise Letecké Opravovne Trenčín (from 2006 transformed to a Joint-Stock Company) has been responsible for the design, production, installation, testing and induction to operational service. The companies Česká Letecká Servisní Praha (ČLS) and Letecké Opravny Kbely (LOK) from the Czech Republic were involved in the modernization. The helicopters with the construction numbers 108M17 and 108M42 functioned as Mi‑17 MODER prototypes as they both came to Trenčín in the year 2001 for Overhaul due to expired Time Between Overhaul (TBO).

The modernization of on-board radio navigation, radio communication and special radio technical equipment results from the requirements for operation in civil airspace according to ICAO and JAR regulations. In March 2004, Slovakia became a NATO member. By installing the on-board part of the Tactical Air Navigation (TACAN) system approved according to MIL‑STD‑291E, route navigation in cooperation with NATO troops will be ensured. The built-in on-board transponder ensures the identification of targets in Mode 1 and Mode 2 for military purposes with the possibility of using Mode 4 according to IFF Mark XII. The modernization also includes equipment with self-defense systems and increasing the combat resistance of the helicopter against infantry weapons by ballistic protection of cockpit, cargo compartment and external fuel tanks. The armament was expanded to include the possibility of using cannon containers UPK‑23‑250.

The first flight of a Mi‑17 MODER was performed on May 20th 2002 and continued with certification and military trials. Second Mi‑17 MODER prototype took off on July 19th 2002. The Mi‑17 MODER was presented to the public for the first time in May 2003 during the Belgian HeliDays at Liege-Bierset.

Immediately after the modernization, from August 2002 till June 2003, first two Mi‑17 MODER helicopters with flying and ground support personnel were deployed in the Stabilisation Force (SFOR) in Bosnia and Herzegovina. They were assigned to the 1st Independent Helicopter Unit under Dutch command and based at the military base in Bugojno.
From December 2007 until June 2008, a Slovak helicopter unit was engaged in the Kosovo Force (KFOR). Deploying with two upgraded Mi‑17 MODER helicopters, the unit was based at Camp Šajkovac, from where it conducted transport and monitoring missions (carrying personnel, VIPs, intervention teams and material). It operated under the direct command of the KFOR headquarters at Šajkovac. The helicopters were equipped with fire-fighting capabilities and ready to intervene whenever forest fires were reported.
In the years 2006-2010, the Slovak Armed Forces took part in Operation EUFOR ALTHEA. During 2009, the Slovak Air Force provided two Mi‑17 MODER helicopters for the period from February to June, which were used for transport, special missions and training flights from their base at Camp Butmir.
