A man accused of being part of an alleged UK terror cell talked about being "trained up" for a "big mission" in the future, a court has heard.
Seven men all deny plotting to cause explosions
The prosecution said the comments by Jawad Akbar could be heard in a bugged conversation it played to jurors.
The 22-year-old from Crawley, West Sussex, was also said to have remarked that he did not pray in public so people would not know he was religious.
He and six other men deny conspiring with a Canadian to cause explosions.
"I might be going in about a month or two's time or a year's time," Mr Akbar was heard to say in the recordings played to the Old Bailey jury.
"I don't want people to know I am religious."
He added: "They're going to train me up and probably send me back here, act like completely stupid and do a big mission."
The defendants were arrested on 30 March, 2004, after fertiliser was found stored in a west London depot.
Mr Akbar, Omar Khyam and his brother Shujah Mahmood, 19, and Waheed Mahmood, 34, of Crawley, Salahuddin Amin, 31, of Luton, Beds, Anthony Garcia, 23, of Ilford, east London, and Nabeel Hussain, 21, of Horley, Surrey, are accused of conspiring to cause explosions likely to endanger life between 1 January, 2003 and 31 March, 2004.
Mr Khyam, Mr Garcia and Mr Hussain also deny a charge under the Terrorism Act of possessing 600kg (1,300lb) of ammonium nitrate fertiliser for terrorism.
Mr Khyam and Shujah Mahmood further deny possessing aluminium powder for terrorism.
