This group of Ushakov medal number 100 was awarded to Ivan Sergeevich Shuravlev of the Soviet Navy.  He was born in 1920 and was raised in a small village outside of Smolensk.  Drafted in 1940, he opted to join the Soviet Navy, and rose to the rank of Chief Petty Officer, serving on motor patrol boats.

He was awarded his Order of the Red Star on 21 July 1944, while serving as the commander of the Motorist Division onboard Motor Torpedo Boat number 25 of the 3rd Division of the Torpedo Boat Brigade of the Baltic Fleet.  On the same citation are the awards of the Red Star to the Commander of Motor Torpedo Boat 25, a Lieutenant Shurpluk, a senior deck sailor from the same boat, and the senior petty officer of the Motorist Division onboard MTB 25.  

On 15 October 1944, he was awarded the medal Ushakov, while still onboard Motor Torpedo Boat 25.  This was the only award to his crew at that time. 

While we do not know what exactly his Ushakov medal was awarded for, we do know that the "Medal of Ushakov" (as it is properly known) was awarded for courage and bravery displayed while defending the USSR at sea, in war as well as peace.  It was awarded to soldiers and sailors, petty officers, non-commissioned officers, chief petty officers and warrant officers of the Navy and Naval Border Guards. 

The first awards of the Ushakov medal took place on 24 April 1944, and the medal was awarded approximately 15,000 times prior to 1991. (Very few awards were for actions other than during the Patriotic War.  Ushakov medals with serial numbers well into the 13,000 range were still being awarded for WW2 actions late in the 1940's.) This example, number 100, was awarded on 15 October 1944.  

Normally, the medal would be issued with a separate medal book.  However, since Chief Shuravlev had previously been awarded the Order of the Red Star in July 1944, the Ushakov medal was simply added into that book.
