A further three men from the West Midlands are due in court charged with terrorism offences.
The men, two aged 22 and one 24, will appear at Westminster Magistrates' Court in London.
The charges follow a series of arrests made last week by the West Midlands Counter Terrorism Unit, assisted by the North East Counter Terrorism Unit.
The trio, who have been charged under section 5(1) of the Terrorism Act 2006, are accused of preparing an act, or acts of terrorism between May 1 and July 4 this year, West Midlands Police said.
Their alleged conduct includes the manufacture of an improvised explosive device, the acquisition of firearms and other weapons, and the purchase of motor vehicles connected with the charges.
Three other terror suspects appeared at the same court on Tuesday charged with similar offences after shotguns, a nail bomb, machetes and a note addressed to a right wing group were found in a car stopped by police on the M1 motorway.
Jewel Uddin 26, Omar Mohammed Khan, 27, and Mohammed Hasseen, 23, were arrested after a routine stop of a Renault Laguna by police near Sheffield on Saturday.
It was alleged that a cache of weapons was found in the vehicle along with a note addressed to the "English Drunkards League", an apparent reference to the far right English Defence League, which was planning a rally in South Yorkshire that day.
The three men, all from Birmingham, face an allegation that between May 1 and July 4 they took part in activities including the manufacture of an improvised explosive device, the acquisition of firearms and other weapons, and the purchase of motor vehicles connected with the charges. They were remanded in custody to appear at the Old Bailey on July 31.
Police said a 43-year-old man from Kirklees, West Yorkshire, who was arrested last week has been released without charge.
