On March 21, 2025, US President Donald Trump announced from the Oval Office that he had directed the American Air Force to move forward with the development of “the world’s first sixth-generation fighter jet .” He was flanked by US Secretary of Defence Pete Hegseth, who went on to boast about the fighter jet’s “speed, manoeuvrability and payload.”
Hegseth said that the fighter jet promises to be something “the likes of which nobody has seen before.” Trump went on to interject his defence secretary, pointing to the name “F-47” for the fighter jet. “Nothing in the world comes even close to it,” Trump said. “It’ll be known as the F-47. The generals picked the title. It’s a beautiful number.”
The announcement of the fighter jet’s name came as a surprise since it was supposed to succeed the F-22 aircraft. Many soon started to wonder if the fighter jet was named F-47 to honour the 47th President of the United States, Donald J Trump. Well, the assessment might be partially true, but there is more to the story. To understand the reason why number 47 was chosen for the new line of fighter jets, let’s first see how the United States names its weapon systems and aircraft.
How do they get the names?
It is pertinent to note that the US military has a longstanding naming protocol for its aircraft. The rules of the game are governed by something called the “Mission Design Series”, established by the Defence Department in the 1960s. “This system uses letters and numbers to symbolise identifying characteristics of military aerospace vehicles of direct interest to the DoD,” an Air Force memo obtained by Bloomberg read.
The first letter depicts the basic mission of the aircraft. For example, the letter ‘B’ denotes that it is a bomber and the letter ‘P’ denotes that it will be used for patrolling. Then there is a dash, which is followed by a number, called the ‘design number’.
According to an article by the US Naval Institute, this number conveys that the “aircraft is a specific design of that particular type or basic mission.” The number tends to follow a sequential pattern. However, the article made it clear that “there are many gaps and numerous exceptions to these sequences.” there are many gaps and numerous exceptions to these sequences.” Since the F-47 is succeeding the F-22, the fighter jet would fall in the exception category.
Honouring history or Trump
When a journalist from Bloomberg filed a Freedom of Information Act request with the US Air Force, he received the real reason behind the naming of the aircraft. The records from the Air Force showed that the name F-47 had its roots in an iconic World War II fighter plane, and the generals also found it an interesting way to honour the current US President.
The records showed that General David Allvin, the Air Force’s chief of staff, had an “urgent” request for information about a World War 2 aircraft. A few hours later, Air Force researchers sent a two-page description of the P-47 aircraft, popularly known as “Thunderbolt”.

In the memo obtained by Bloomberg, the US Air Force described the P-47 as “probably the best ground-attack aircraft fielded by the United States. From D-Day, the invasion of Europe launched on June 8, 1944, until VE Day on May 7, 1945, pilots flying the Thunderbolt destroyed the following enemy equipment: 86,000 railway cars, 9,000 locomotives, 6,000 armoured fighting vehicles, 68,000 trucks.”
How the Air Force was left by surprise by Trump’s announcement
When Trump announced the F-47 jet, neither he nor Hegseth mentioned the legacy of the P-47. Bloomberg’s assessment showed that there is a possibility that the Air Force may have been caught off guard or were just unprepared when the president said the new fighter jet would be called F-47.
It is pertinent to note that Trump’s press conference took place at around 11:30 am (local time). The email obtained by the news outlet showed that they were sent soon after the presser. “Sir, Request coordination with SECDEF office,” an Air Force public affairs official wrote in an email sent to Lieutenant General Dale White, the military deputy in the Air Force’s Office of the Assistant Secretary for Acquisition, Technology, and Logistics.
However, General Allvin’s team dismissed the claim that the decision to honour P-47 was taken after Trump’s announcement. At least one reporter pressed an Air Force spokesperson for more details about the “designation for the F-47.” “The nomenclature system exists to maintain an orderly, non-chaotic process of naming systems,” the reporter asked. “Why was it abandoned in this case? And who decided to do that?” the reporter asked.
Ann Stefanek, the Air Force spokesperson, did not share additional details on the matter and just remarked: “General Allvin made the decision.” It will now remain unclear exactly when the decision to honour the aircraft was taken.
