BAHNA 2023 // Mi-171ŠM
While the first helicopters of the Mi-8/17 family (NATO code name: "Hip") appeared in the Czechoslovakian army service already in 1967, the pictured machine is a deep modernization of one of the 16 Mi-171Š (Mi-171Sh) helicopters the Czech Republic received in 2005 from Russia as part of the settlement of outstanding debts of the former Soviet Union and the Russian Federation.
Mi-171Š is an export variant of the Russian Mi-8AMTSh. Compared to the older Mi-17's the Czech Air Force still operates, these have an upgraded engines, a new large doors on the right side and additional armour around cockpit area and the engines. Part of these machines are also equipped with a rear hydraulic ramp in contrary to the usual clamshell doors. But in addition to that, the Czech Mi-171Š went through a several modernization programs thrughout their service, after which these machines are often designated as Mi-171ŠM.
The one in the picture is one of the Mi-171ŠM (ramp version) earmarked for "Special Operation Air Task Unit" (SOATU). At first, such machines have been modernized to the so-called "SOF II standard", which includes for example a new communication and navigation systems, installation of coutermeasures against ground-to-air and air-to-air missiles, a new multifunction displays in cockpit, and more. Some of the machines also received nose-mounted electro-optical and infrared multisensor surveillance system Star Safire III with weather-radar, as well as mounting for 7,62mm Dillon M134D-H rotary machine guns. The modernization then continued in the last years with better ballistic protection of the cargo area, upgrade of the cargo area to be compatible with NATO pallet system as well as installation of a new crane with greater capacity. Eventually, the rest of Mi-171ŠM helicopters, which are not desiganted for the SOATU, will be modernized to the same-level standard as well.
These upgrades would enable the Czech Mi-171's to continue operating at least until 2035, when they were originally expected to be phased out, but the new security situation in Europe after the major escalation of War in Ukraine changed the plans and now there are talks abour their retirement already in 2030. The CH-47F Chinook is being talked about in military circles as a possible replacement of the Czech Mi-171's, although it is not the only one.
