Gary Davis Title: The UK telescopes on Mauna Kea: breaking news and future prospects Abstract: For over two decades, the United Kingdom has operated two highly-productive telescopes on Mauna Kea: UKIRT and the JCMT. Both have been through major transformations in recent years. UKIRT has evolved from a general-purpose facility offering a comprehensive suite of capabilities to a tightly-focussed survey telescope, with WFCAM as its sole instrument and UKIDSS as its dominant programme. For the JCMT, the SCUBA-2 instrument is in the final stages of commissioning and will be released to the community at the end of September, at which point the partner countries will embark on a new programme called the JCMT Legacy Survey. In this presentation I will describe these evolutionary changes and the prospects for the future of both observatories
