Does anybody know what ship HR 945 refers to?

I have been researching my grandfather's WWII history and have been able to get copies of many of the morning reports from his unit, the 444th Bomb Group.  Several of the morning reports mention being at sea on HR 945 and one dated 12 Feb 43 indicated they embarked on HR 945 for overseas shipment from Newport News, Virginia.  A later report dated 11 March 43 indicates they left staging area #2 in Oran and travelled by motor convoy 20 kilometers to Oran Harbor where they boarded the SS Champoleon.  Another report indicates they were docked in the Harbor of Naples on 15 Mar 43 where they underwent an aerial bombardment at approx 0130 lasting 20 minutes.  I am trying to find what ship HR 945 refers to - it seems they boarded the SS Champoleon at Oran, but what ship took them from Newport News to Oran?  Also, does anybody know anything about the aerial bombardment they faced? 
 
Any input would be appreciated...
 

Thanks for the suggestion.  Doing a search using the link to the site you included does not list any convoy beginning with HR but it may not be all inclusive.  Does anybody else have any ideas on how to further research this?
 

HR945 does not refer to a single ship.It is a convoy number. A convoy could consist of a few ships to hundreds. Many ships formed up at Newport news, a lot from Gulfport States. My guess because of the odd number (larger convoys had HX, SC,ON, etc) and the fact that he must have been on a troop carrier, only a few fast ships in the convoy. Troops were usually carried over on fast ships that could out run the slower U-Boat. I've got a list of a lot of convoys, but HR945 is not amongst them.
I recall there was a unit or two that passed through Italy and ended up in the far east.

Sorry for that - too many dates.  It was 1944, not 1943.
I am trying to track the movements of my grandfather and his units.  Here is the path I've been able to trace by reading through morning reports.  I have a number of questions and if anybody can help answer or fill in any blanks please do.
*1 Aug 43 679th B.S. Davis Monthan Field, Tuscon Az, entrained to travel to Great Bend, KS.
*3 Aug arrived Great Bend
Then no mention in morning reports until 5 Dec 43 when my grandfather and other members of the 679th are transferred to the 8th Bomb Maint Sqd and the 679th deactivated????  Why did they deactivate?
*12 Feb 44 From Camp Patrick Henry, VA  arrive at Newport News, VA by rail and embark on HR 945 for overseas shipment with 14 officers and 338 enlisted men.
Then there are a few unreadable pages.  Next:
*10 Mar 44 Left staging area #2 Oran atchd Natousa at approx 1400 and traveled by motor convoy 20km to Oran.  Boarded SS Champoleon in Oran Harbor.  Boarded Champoleon here - I'm trying to find what ship brought him from Newport News. 
Where was staging area 2 and what/where is Natousa?

*28 Nov 44 grandfather - Fr Dy to Sk 372nd Sta Hosp APO 493.  Would this have been a transfer or was he hospitalized - I'm not sure how to read all of the abbreviations?
Next morning report mentioning him is :

I realize this is lengthy but again, if anybody can answer any of the questions or offer any info please do.
