A teenage extremist who 'hated Jews and Muslims' didn't realise he was discussing his plans for a racist revolution with an undercover officer, a court has heard.
Matthew Cronjager, 18, of Ingatestone, Essex, is accused of drawing up plans for a storage bunker and giving instructions and funds for the manufacture of two firearms - an 'FGC-9' and a 'Cheetah' - using a 3D printer.
Alistair Richardson, prosecuting, said: 'He made plans for storage of firearms, in preparation for his violent acts, and he provided instructions and funds to others, in order to secure the manufacture of a firearm.
'Unknown to him, the person he was providing instruction to and funds to, was, in fact, an Under Cover Law Enforcement Officer (a UCO).'
Cronjager is said to have transferred funds to help purchase materials to build weapons between 31 October and 19 December 2020.

Mr Richardson, prosecuting, told a jury at the Old Bailey: 'As of 2019-2020 he held radical, extreme right wing beliefs. To use his own words, fascist, beliefs.
'He wanted to bring about a change of government by violence.
'He hated people of different colour skin, he hated Jews, he hated Muslims, he hated people of different sexual orientation to his own.
'He hated Asians who had sexual intercourse with white people. He wanted to bring about his own revolution, based on his own racist ideology. To that end, he sought to produce a firearm, using a 3D printer.'
Cronjager allegedly collected extreme right-wing propaganda and manuals to help him spread his radical views on a Telegram channel called 'Exiled 393 library'.
Mr Richardson added: 'Some of the manuals he downloaded provided real and practical guidance to those who would wish to commit terrorist atrocities.

'In furtherance of his cause, he set up an online library, where he, and those of a like mind, could store their propaganda, and their manuals in furtherance of their cause.'
Cronjager denies engaging in conduct in preparation of terrorist acts.
The charge alleges that 'with the intention of committing acts of terrorism engaged in conduct in preparation for giving effect to that intention, namely, drew up plans for a storage bunker, provided information for the manufacture by a 3-D printer of two firearms, namely a FGC-9 and a Cheetah and transferred funds to another for the purchase of materials to manufacture those firearms'.
The teenager also denies dissemination of terrorist publications in relation to the 'Exiled 393 library' Telegram channel.
He admitted four counts of collecting information likely to help others preparing an act of terrorism - including 'The KGB Alpha Team Training Manual'; Workbench Silencers - The Art of Improvised Designs' by George Hollenback; 'Ragnar's Big Book of Homemade Weapons.pdf and;Expedient Homemade Firearms'.
