Mae Llywodraeth Cymru yn gweithio i ddatblygu ail gam y cyfleuster ar safle gwahanol yn y Gogledd. Ym mis Gorffennaf, cyhoeddodd Llywodraeth Cymru ei bwriad i weithio gyda Bwrdd Ardal Fenter Glannau Dyfrdwy a’r Weinyddiaeth Amddiffyn, o dan arweiniad y Defence Electronics and Components Agency (DECA), ar gynnig i leoli ail gyfleuster ar dir wrth ymyl Cyfnewidfa Parc Diwydiannol Glannau Dyfrdwy.
The Welsh Government is working to develop the second phase of the facility on a separate site in North Wales. In July the Welsh Government declared its intention to work with the Deeside Enterprise Zone Board and the Ministry of Defence, led by the Defence Electronics and Components Agency (DECA), on a proposal that would see  a second site  situated on  MOD land adjacent to the Deeside Industrial Park Interchange.
