A further three men from the West Midlands are due in court on Wednesday 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.
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. Jewel Uddin 26, Omar Mohammed Khan, 27, and Mohammed Hasseen, 23, were arrested on Saturday.
The three men, all from Birmingham, face an allegation that 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 alleged plot.
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.
