Prosecutors are to continue setting out their case at the Old Bailey against seven British citizens accused of plotting terrorist attacks in the UK.
The men, one of whom cannot be pictured, deny all the charges
Their potential targets are alleged to have included pubs, clubs and trains.
The men, four from Crawley, West Sussex, one from Horley, Surrey, one from Ilford, east London, and one from Luton, Bedfordshire, deny all charges.
Four of the men also deny having chemicals suitable for bomb-making. The trial is expected to last five months.
On Tuesday, prosecutor David Waters QC said the men had acquired "most of the necessary components" to launch a bombing campaign, with 600kg of ammonium nitrate fertiliser and a smaller amount of aluminium powder recovered by detectives.
But he said police had intervened before the plot "reached fruition".
Mr Waters told the jury they would be hearing from an American citizen, Mohammed Babar, who conspired with the defendants.
Babar has pleaded guilty to terrorism offences in the US and, according to the prosecutor, "has an insight as an insider into the events and plans which an outsider could not have".
It is claimed Babar met several of the defendants in England and in Pakistan, where many of them have family connections.
Mr Waters said the defendants' "principal purpose" in travelling to Pakistan was "to acquire expertise in relation particularly to explosives".
Omar Khyam allegedly proposed pubs and nightclubs as targets
It was during a meeting with Babar that 24-year-old defendant Omar Khyam, from Crawley, allegedly told Babar his targets could include pubs, nightclubs and trains.
Mr Waters said Mr Khyam's motive was clear: "The UK was unscathed, it needed to be hit because of its support for the US."
The prosecutor said Mr Khyam and co-defendant Salahuddin Amin, 31, of Luton, both told Babar they worked for a man who they claimed was "number three in al-Qaeda".
On the first day of the trial, Mr Waters told the jury the plot was stopped before it could reach fruition.
"The interception came only when most of the necessary components were in place," he said.
"All that remained before their plans achieved their ultimate goal was for the target or targets to be finally agreed."
He said each of the men "played their respective roles" in a plan to get bomb-making ingredients.
The bomb, or bombs, would have been used "at the very least to destroy strategic plant within the United Kingdom, or more realistically to kill and injure citizens of the UK", alleged.
Mr Khyam and his brother Shujah Mahmood, 19, also from Crawley, each deny possessing aluminium powder.
Mr Khyam, Anthony Garcia - also known as Rahman Adam -, 23, of Ilford, and Nabeel Hussain, 20, of Horley, each deny possession of ammonium nitrate fertiliser.
The other accused are Waheed Mahmood, 34, and Jawad Akbar, 22, both from Crawley.
All seven deny a charge of conspiracy to cause explosions.
