Jorma Karhunen (17 March 1913 – 21 January 2002) was a Finnish Air Force ace and an author.

He scored 31.5 kills in World War II; 25.5 of his air victories were achieved while flying the Brewster F2A Buffalo, American fighter.

Soon after the outbreak of Operation Barbarossa, on 25 June 1941, when he was 1st Lt, Karhunen led the 3rd Flight (of eight Brewster Buffalo) of Lentolaivue (LLv) 24, based at Vesivehmaa.

On 9 July, he was one of the dozen Brewster pilots led by Major Gustaf Magnusson on a patrol over Lahdenpohja, that in a ten-minute air combat shot down eight out of 15 Soviet bombers and fighters 
At the end of July, his 3/LLv24 was ordered to  support the offensive against the Karelian Ishtmus, scheduled for 31 July.
Karhunen unit's opponents were 5th SAD, 7th and 153rd IAP and 65th and 235th ShaPs.

On 1 August Karhunen's unit of seven Brewsters shot down six I-16s near Rautjarvi, WO Ilmari Juutilainen, claiming two of them.

Eleven days later, on 12 August, Capt Karhunen was involved in the heaviest air combat over the Karelian Isthmus, while leading six Brewsters from 3/LLv 24 on a patrol.
On Antrea area they attacked a formation of about 20 aircraft from 65th ShAP.
During the ensuing 30 minutes air combat, Karhunen and his pilots shot down nine Polikarpov I-153s "Chaikas".

On 26 September, Soviets suffered further losses.
That day, Capt Karhunen's formation of seven  Buffalos shot down six I-15s north of Petajaselka.
 The Finnish came back in the area a short while later and encountered eight I-15 bis from 65th ShAP.
The Brewster pilots shot down three of the enemy aircraft.

Capt.
Karhunen later recalled:
On 26 September 1941, Karhunen claimed two I-153, his fourth and fifth air victories: 
While carrying out a reconnaissance mission over Mikonselka railway station.
I saw three I-153s flying beneath the clouds, southeast of  Petajaselka.
Diving after them... I singled out the fighter to the left of the formation.
I shot it down  in flames in the forest with just a few burst of fire.
After pulling up, I saw a second I-153 at low-level flying in a southeasterly direction four kilometres south of where my first Chaika had crashed.
Getting on its tail, I fired at the I-153 from a distance of 100 metres.
It clipped the treetops and crashed, although on this occasion it didn't burn.


After the end of hostilities, Karhunen, the captain and commander of the 3rd flight of LeLv 24, recalled: 
The Brewster model 239 was good against the older Russian fighters, Polikarpov I-153 Chaika (Gull) and I-16.
Hence the period 1941–42 was the best time for us.
In 1943 it was already significantly more difficult when the Russians began to use their newer fighters against us... Later, with the Yaks, Hurricanes, Tomahawks, LaGG-3 and MiGs, it became a fight to the death.

He retired from active duty on 13 December 1955.

During his retirement years Jorma Karhunen wrote 36 books in Finnish, mainly about aerial combat in the wars between Finland and the USSR.
The books were published between 1958 and 2000.
As an author, Jorma Karhunen used an alias Joppe Karhunen.
