We certainly welcome this collaboration and wish to bring it to a successful conclusion. The timetable that my hon. Friend asked about is as follows. After the exploratory period of 18 months, we hope to proceed by mid-1993 with full development, leading to a first order by the mid-1990s. We aim for an in-service date in the early years of the next century. As for equipment, part of the purpose of the exploratory work is to agree a memorandum of understanding to cover all procurement aspects.
