Lockheed C-130 Hercules

| Wednesday, May 25, 2011 | 0 comments

The Lockheed C-130 Hercules is a four-engine turboprop military transport aircraft designed and built originally by Lockheed, now Lockheed Martin. The C-130 Hercules is arguably the most versatile tactical transport aircraft ever built. Its uses appear almost limitless: airlift and airdrop, electronic surveillance, search and rescue, space-capsule recovery, helicopter refueling, landing (with skis) on snow and ice, and aerial attack. It has even landed and taken off from a carrier deck without benefit of arresting gear or catapults. Capable of using unprepared runways for takeoffs and landings, the C-130 was originally designed as a troop, medical evacuation, and cargo transport aircraft. The versatile airframe has found uses in a variety of other roles, including as a gunship (AC-130), for airborne assault, search and rescue, scientific research support, weather reconnaissance, aerial refueling, maritime patrol and aerial firefighting. It is the main tactical airlifter for many military forces worldwide. Over 40 models and variants of the Hercules serve with more than 60 nations.

During the 1950s the versatile Lockheed C-130 Hercules was originally designed as an assault transport but was adapted for a variety of missions, including: special operations (low-level and attack), close air support and air interdiction, mid-air space capsule recovery, search and rescue (SAR), aerial refueling of helicopters, weather mapping and reconnaissance, electronic surveillance, fire fighting, aerial spraying, Arctic/Antarctic ice resupply and natural disaster relief missions.

Currently, the Hercules primarily performs the intratheater portion of the tactical airlift mission. This medium-range aircraft is capable of operating from rough, dirt strips and is the prime transport for paratroop and equipment drops into hostile areas.
