History

The Imperial Japanese Army (IJA) initiated plans to develop the existing airfields at Lampang and Ko Kha, and also the establishment of two new airfields in Mae Mo and Hang Chat. When completed, the complex would be able to support the plans of the IJA to defending Burma, then to invade India, and finally in the defense of Thailand as well. There were other airfields located in Chiang Mai, Chiang Rai, Phrae, Nan, and Kengtung, which operated subordinate to the Lampang complex. By 1944, an airfield at Hang Chat and Mae Mo was completed, however, no aircraft has been sighted at both airfields. This was caused by Japan's aircraft industry being plundered from Allied air attacks. [1]

Airfields

Lampang and Ko Kha had already existed prior to the war, and Mae Mo and Hang Chat were built later on. The following lists all airfields and their history. [1]

Lampang

Coordinates: 18°16′15″N99°30′15″E / 18.27083°N 99.50417°E / 18.27083; 99.50417

Lampang Airfield was initially established on 7 November 1923, and later operated as a Royal Thai Air Force base. It operated as the main airfield of the complex. It operated air transportation. In March 1940, the US War Department report listed Lampang Airport as a military landing ground. The airport was operated and maintained by the Royal Thai Air Force. On 7 December 1941, the US Army Air Corps reported Lampang Airport with 2 hangars and a grass runway. On 12 December 1941, Lampang Airport was occupied by Imperial Japanese Army troops. On 22 March 1942, Lampang Airport was being developed into a heavy bomber airfield. In early 1942, Lampang Airport was heavily crowded with IJAAC and RTAF squadrons, totaling 47 aircraft. The squadrons led multiple bombing missions at a Nationalist Chinese 93th Division military base in Loi Moei, where 11,000 troops were based. [2]

Units

The following lists the units based in Lampang Airfield.

Ko Kha

Coordinates: 18°11′44″N99°24′29″E / 18.19556°N 99.40806°E / 18.19556; 99.40806

Ko Kha Airfield initially operated as a Royal Thai Air Force base. In 1937, it served as the headquarters for the Wing 80. On 22 December 1941, the 61st Squadron RTAF was based in Kho Kha equipped with Nakajima Ki-21 heavy bombers. It later moved out in 1943. In October 1943, 10 aircraft shelter accommodations were reported to be built. In October 1943, Ko Kha Airfield began heavy upgrades, including the runway being extended by an additional 150-200 yards. By 30 April 1943, 10 additional aircraft shelters had been built. Throughout the year, no aircraft had been reported to be operating out of the airfield. However, by 31 December 1943, the number of shelters had totaled to 32. [3] By March 1944, the airfield's capacity was readied to occupy an estimate of two squadrons of light bombers. There was also an extensive development of taxiways underway. In November 1943, it was noted that Japan had been focusing on the development of their bases in Thailand with greater attention rather than their positions in Burma. An ammunition ordnance facility, a fuel and oil facility, and a general storage facility had been built. Living accommodations were also constructed. By May 1944, Ko Kha Airfield was reported to be completed with an all-weather airfield, with development efforts ceasing. [4]

Post-war

In 1945, Ko Kha Airfield was abandoned by the Japanese. No aircraft had been sighted during its Japanese occupation. In the 1950s, the airfield was still operational, however it was listed as closed by 1968. [5]

In 1971, a USAF space track radar was established on the site of the airfield, named Ko Kha Air Station. It consisted of various facilities including a dining hall, radar system, and enlisted men's barracks. The 17th Radar Squadron was stationed. [6] It was closed in 1976, with the radar being dismantled. [5]

The South-half of the old runway has been developed into an industrial park. In 2013, the King Narai Plaza monument was completed on the south end of the former airfield. In 2014, a natural history museum also began construction and was completed in 2015. Nothing significant is left of the former Ko Kha Airfield. [5]

Hang Chat

Coordinates: 18°16′15″N99°30′15″E / 18.27083°N 99.50417°E / 18.27083; 99.50417

Hang Chat Airfield, also known as Lampang NW is the Westerly satellite airfield in the Lampang Airfield Complex. It begun construction in August 1944 by the Japanese Army. Upon their arrival, they first hired local Thais to construct huts for them, located in wooded areas isolated from nearby villages. It consisted of a wood framed, roofed with canvas and floods of milled wood. After the completion of the huts, many Thai laborers were recruited to construct the runway. Trees were sawn down by hand, and stumps were burnt and filled. After one year of construction, Hang Chat airfield was finally activated. It consisted of two parallel runways separated by approximately 400 yards (365 m), however the Easterly runway was not serviceable. In October 1944, the Eastern runway was being surfaced, where construction effort would be focused on the runway through 15 December. It consisted of 6 aircraft shelters, and revetment walls begun being installed. As observed by Allied intelligence, Hang Chat Airfield was expected to become operational with aircraft, pilots, and ground personnel. By March 1945, the airfield has 12 surface-rolled aircraft shelters. By 31 May, Hang Chat Airfield was reported to be disused by the Japanese. [7]

Post-war

After the war, the Japanese left, leaving Hang Chat Airfield abandoned. The runways quickly became overgrown, and were cleared in adjacent areas for farming.The airfield was not depicted in any post-war maps. In 1966, the US Coast Guard established a LORAN transmitted located 4.5 km southwest of the center of the Hang Chat runways to aid navigation during the Vietnam War. This proximity to the former airfield is only mere coincidental. [8]

Additionally, there was a Highway strip bearing the same name, which was first projected in 1973. It was the Hang Chat Highway Strip, which may have never been implemented at all due to the steep grading of the highway. [8]

Hang Chat LORAN

The LORAN station itself was constructed from June to September 1966 by the United Construction Company, and the tower was supplied by the Chicago Bridge and Iron S/P and Subsistence buildings: H. H. Robinson Co. It consisted of multiple buildings. It was activated on 18 August 1966 and was operated by the USCG. The commissioning commenced with a religious ceremony and military parade. [9] It was deactivated on 17 September 1975. [10]

Mae Mo

Coordinates: 18°24′46″N99°43′42″E / 18.41278°N 99.72833°E / 18.41278; 99.72833

Mae Mo Airfield was the easterly satellite airfield in the Lampang Airfield Complex. The Imperial Japanese Army Air Force begun the construction of Mae Mo Airfield in April 1944. Portions of thick jungle had to be cleared by engineers. Located North of the airfield was a temporary living accommodation. On 19 June 1944, four 22nd Bombardment Squadron B-25s of the 341st BG took off to attack Kenghluang Railway Tunnel in Thailand. However, they observed Mae Mo Airfield, which was bombed by accident. Numerous reconnaissance missions have been made to photograph the airfield, in which most resulted in failure due to cloudy weather conditions. [11]

In April 1945, Mae Mo Airfield was reported to be disused by the IJAAF. When the war ended, the surrounding forests were cut down. What remained of the runways disappeared into rice fields that now covers the area. There were two bomb craters which are still visible, and one additional bomb which remained unexploded. It was later retrieved by the Thai government. [11]
