Tsili Tsili Airfield is located at Tsili Tsili (pronounced Silly-Silly) in New Guinea. Sometimes spelled Tsile-Tsile. The Japanese referred to this area as "Fabua". Today, also known as "Gomorok". To the east is the Watut River and to the southeast is Marilinan (Maralinan). Tsili Tsili is roughly forty miles from Lae.

Prewar and during the Pacific War part of Morobe District in the Territory of New Guinea. Today located in Morobe Province in Papua New Guinea (PNG).

The area was occupied in the middle of June 1943 and quickly developed into a forward airfield for operations against Lae by the U.S. Army AIr Force (USAAF) 871st Airborne Engineers. The airfield had two intersecting runways. The main runway was 5,000' x 125' oriented SW to NE with an extension of graded dirt. The second runwy was 4,700' x 225' oriented 14/32 northwest to southeast. Both runways were connected by taxiways and hardstands for aircraft dispersal. All supplies, food, fuel and equipment had to be flown into via C-47 Skytrains from Port Moresby. To the southeast was Marilinan Airfield used as an emergency strip and to confuse any Japanese aerial observation about the size of the base and which was the main runway.

Wartime History
On July 26, 1943 the first fighters were based at Tsili-Tsili Airfield. General George C. Kenney wanted the field renamed, as he thought Tsili Tsili was demeaning and of propaganda value if the location was captured. On August 5, 1943 the newly formed Second Air Task Force under the command of Lieutenant Colonel Malcolm A. Moore is established at Tsili Tsili Airfield.

On August 11, 1943 a Japanese reconnaissance plane discovers Tsili Tsili Airfield. On August 15, 1943 the Japanese Army Air Force conducts their first air raid with seven Ki-48 Lilys escorted by Ki-43 Oscars. Over Tsili-Tsili area, the Japanese formation is intercepted by P-39 Airacobras escorting C-47s to Tsili-Tsili and the Japanese suffer heavy losses and only manage to inflict minor damage.

Walter Seale from the 871st Airborne Engineer Battalion adds:
"A lot of cripples landed at Tsilli-Tsilli and later Gusap. They were either low on fuel or shot-up and couldn't be sure of getting home safely. We also mowed a fake runway nearby to confuse the Japanese to make them think the base was bigger than it actually was."

Japanese missions against Tsili Tsili
August 15, 1943–September 13, 1943

The airfield has been abandoned since the war. Until the early 1970s there were several wrecks at the strip, four P-39s and a P-40 abandoned there.  Three aircraft were recovered by Monty Armstrong and Charles Darby in 1973 for Yesterday's Air Force.

Richard Leahy adds:
"Tsili Tsili strip is still there although probably in need of mowing. I have carried out a lot of work to and from Tsili Tsili over the last forty years."
