También cancelaron que el entrenamiento lo hiciera la ANG de Oregón y ahora lo hara la 4th FW Activa.

Boeing entregó otros dos F-15EX Eagle II a la Fuerza Aérea de EE. UU., un año más tarde de lo esperado originalmente.
Tal como están las cosas ahora, la Fuerza Aérea ha anunciado oficialmente planes para establecer tres escuadrones operativos de F-15EX, uno dentro de las Guardias Nacionales Aéreas de Oregón, California y Luisiana, donde reemplazarán a los viejos cazas F-15C/D Eagle.

Nikkei Asia , la revista de noticias con sede en Japón, informó hoy que el Pentágono planea desplegar permanentemente 36 cazas F-15EX en Kadena. Se dice que la fuente de esta información son “fuentes del Congreso” anónimas que, según Nikkei Asia, fueron informadas sobre el plan.

Cost overruns on B-21 development generate $1.5bn charge for Northrop

While US manufacturer Northrop Grumman only recently secured approval to begin production of the B-21 Raider, the company is already enduring some financial pain from the programme.
Northrop reported it was charged $1.56 billion by the US government in the final quarter of 2023, related to cost overruns on B-21 development.
Northrop cited “macroeconomic disruptions”, including price increases from parts suppliers and higher-than-projected manufacturing costs on the first B-21 example, as the cause of the charge.

The US Air Force (USAF) has imposed strict price limits on the B-21 programme, with an eye toward protecting its acquisition target of at least 100 aircraft.
The gargantuan $2.2 billion per-aircraft cost of the earlier Northrop B-2 Spirit programme forced the USAF to limit its acquisition of that stealth bomber to just 20 aircraft.
Learning from that example, the USAF contracted with Northrop for a target price of $500 million per B-21, in 2010 dollars. That equates to $707 million per aircraft in 2023 values, according to the US government’s Bureau of Statistics.

When contractors exceed cost targets or miss development schedules, the Pentagon can apply penalty charges, depending on the terms of each contract. The recent $1.56 billion charge on B-21 development led Northrop to a $535 million loss in the fourth quarter of 2023. The company posted a profit of $2.1 billion for the entirety of 2023.

The Pentagon approved the B-21 for low-rate initial production (LRIP)... As is typical with aircraft development programme, manufacturers typically see thin margins on LRIP contracts – which carry low-volume orders and higher production costs. “We now believe it is probable each of the first five LRIP lots will be performed at a loss,” Northrop says.

The company has previously said it is assembling six B-21 jets, including the prototype known as T1 that is undergoing flight testing.
