The 78th anniversary of the bombing of Katherine will be held at the museum on Sunday, March 22 from 10am.
Japanese bombers dropped between 80 and 90 bombs on the NT outback town in March 1942, killing one man but changing the town forever.
Four survivors Juanita Heparia, Fay and Les Cox and Neila Boyle will be at the centre of this year's commemoration.
Administrator of the Northern Territory, Vicki O'Halloran, will also be in attendance.
"This year we are honouring people that were present the day Katherine was bombed," manager of the Katherine Museum, Simmone Croft said.
"Despite Katherine being the furthermost point inland to be bombed, a lot of people are unaware it happened at all.
"It is our history and it is good to recognise the service people who assisted and remember Dodger Kodjalwal, the only fatality."
Although Darwin suffered many more raids, this one raid led authorities to rush families to South Australia to safety and signalled an even greater military build up in Katherine, remote from any possible invasion force.
It was the furthest encroachment of enemy invasion ever recorded on mainland Australia but most people have never heard of it.
On March 22, 1942, nine "Betty" bombers from the Japanese Navy dropped between 82-92 high explosive bombs, "Daisy Cutters", as they were popularly known.
There was a large buildup of military personnel at Katherine during World War II.
It is presumed the Japanese were hoping to find either Australian or US aircraft at the Katherine airfield, which they failed to do but dropped most of their bombs in and around the airfield, location of today's museum.
There was one fatality, an Indigenous man called Dodger Kodjalwal, and two other Indigenous people were slightly injured.
Some of the bombs fell at Knotts Crossing, just missing a telegraph line crew and few more targeted the airfield in the bush at Manbulloo.
