Narrative:
Level at 16000 ft MSL, we requested a 120 degree heading to avoid thunderstorms along our route. Controller gave us a 160 degree vector direct publication, which was no relief. Then we requested alternate routing to gld and pnh. Controller vectored 140 degrees due to den arrs. We complied until 12 NM of a thunderstorm cell, then advised controller we needed to come left 090 degrees for WX. He denied our request. We told controller that we were declaring an emergency our heading was 090 degrees east. He acknowledged and we were on a clear path 10 NM later. He then cleared us direct gld with a frequency change. No other discussion was made with ARTCC on this event. Controller was extremely busy with other aircraft during this entire occurrence.

Title: C130 MIL CREW IS FORCED TO DECLARE AN EMER TO AVOID A TSTM IN ZDV CLASS E AIRSPACE.
Narrative: LEVEL AT 16000 FT MSL, WE REQUESTED A 120 DEG HDG TO AVOID TSTMS ALONG OUR RTE. CTLR GAVE US A 160 DEG VECTOR DIRECT PUB, WHICH WAS NO RELIEF. THEN WE REQUESTED ALTERNATE ROUTING TO GLD AND PNH. CTLR VECTORED 140 DEGS DUE TO DEN ARRS. WE COMPLIED UNTIL 12 NM OF A TSTM CELL, THEN ADVISED CTLR WE NEEDED TO COME L 090 DEGS FOR WX. HE DENIED OUR REQUEST. WE TOLD CTLR THAT WE WERE DECLARING AN EMER OUR HDG WAS 090 DEGS E. HE ACKNOWLEDGED AND WE WERE ON A CLR PATH 10 NM LATER. HE THEN CLRED US DIRECT GLD WITH A FREQ CHANGE. NO OTHER DISCUSSION WAS MADE WITH ARTCC ON THIS EVENT. CTLR WAS EXTREMELY BUSY WITH OTHER ACFT DURING THIS ENTIRE OCCURRENCE.
