  The Yakutsk Extensive Air Shower Array has been continuously operating for
more than 50 years (since 1970) and up until recently it has been one of
world's largest ground-based instruments aimed at studying the properties of
cosmic rays in the ultra-high energy domain. In this report we discuss results
recently obtained at the array - on cosmic rays energy spectrum, mass
composition and directional anisotropy - and how they fit into the world data.
Special attention is paid to the measurements of muonic component of extensive
air showers. Theoretical results of particle acceleration at shocks are also
briefly reviewed. Future scientific and engineering plans on the array
modernization are discussed.
