2-6 February 1966 February 7 is the official start date. Battalion arrives on multiple flights in Vietnam after a brief fueling and staging period at Clark AFB, in the Philippines.  Camp Adenir was named after an MCB-9 Seabee, SD2 Restituto P. Adenir, of Cavite City, Philippines, who was KIA in Danang, Vietnam, on 29 October 1965. Shared the Camp with Bravo Company, USMC Military Police.

Staffed the Provisional Platoon made up of Seabees from NMCB-11 who patrolled the nearby Vietnamese villages of My Thi and My Khe. Battalion worked on the following projects. Completed expansion of the Naval Support Activity (NSA) Hospital started by NMCB-9 in the Marble Mountain Military Complex: i.e., built an x-ray building, fire station, generator building, several new Quonset-type wards and improved roads, a Helicopter landing pad and parking areas.  Other projects included: road system for LAAM site and AFRTS building and tower sites on Monkey Mountain; operated the rock crusher; provided a well-drilling crew; replaced three war damaged sections of the Tourane River Bridge, on Rt. #1 south of Danang; worked on a DeLong Type floating pier; installed huge modular steel-framed buildings at the Covered Storage (CS) and Transportation and Maintenance (T&M) sites; completed the canopy for III MAF Officer’s Club patio; completed the III MAF R&R Center; designed and completed the China Beach R&R Site complete with 480-seat outdoor amphitheater; and worked on other projects too numerous to list.

1-5 March 1967 A real-life Seabee-Vietnamese village was set up at CBC Port Hueneme to celebrate the 25th Anniversary of the Seabees and the 100th Anniversary of the Civil Engineer Corps. SEA huts, POL tanks, timber bridges, well-drilling equipment, and strongback tents were set up to resemble a Seabee camp in Vietnam. Seabee Teams—including Seabee Teams 0910, 1010 and 1109—helped set up the camp as part of their real-life training duties. The 29 Palms U.S. Marine Corps band performed music.  Battalions in homeport participated in a full-dress Pass in Review (PIR) on the CBC Grinder.

26 April 1967 Homeport military training cycle was completed. Battalion deployed by USAF aircraft to Dong Ha, Vietnam, to begin their second consecutive deployment to the war zone. Dong Ha was located in the Northern I Corps, about 13 miles from the DMZ between North and South Vietnam. This was the northernmost site that the Seabees deployed to in Vietnam.  Battalion worked on various projects in Dong Ha including: construction and support for Ammunition Depot, Dong Ha Air Base, Seabee Camp, Fleet Logistic Support Unit (FLSU), 500-man messhall, hospital roads and drainage, twenty-eight (28) 50-foot observation towers, various Quonset huts, and other USMC-related work in the area.  Detachments (Details) were deployed to Khe Sanh, Cua Viet, Lang Vei and Gio Linh.  Enemy attacks on the Dong Ha Combat Base and battalion detachment were too numerous to mention on an individual base. A summary of attacks is included at the end of this deployment schedule.

The NMCB-11 Detail at Gio Linh was at the easternmost edge of the “Barrier” (a belt of terrain 600 yards wide strip of land south of the DMZ where all vegetation was being flattened to prevent infiltration by NVA who kept slipping into the DMZ). Gio Linh was a sandbagged, dug-in, heavily wired and mined outpost within easy sight of the North Vietnamese guards and their red flag on the Ben Hai River.  Other Details were at Khe Sanh, at the extreme northwest corner of South Vietnam on the border of Laos, and Lang Vei, five miles closer than Laos.

3 September 1967 A significant day in Battalion history. Frequent and heavy North Vietnamese and Viet Cong artillery attacks on the Dong Ha Combat Base resulted in a massive explosion in the U.S. Military Ammunition Depot which resulted in an 8-hour period of concussion and shock waves from the fires and explosions.

A total of 35 Seabees were awarded Purple Hearts as a result of being WIA during that enemy attack on 3 September.
 
October 1967 Four men from the Battalion received Bronze Star Medals with Combat “V” for their action in combating a fire in the FLSU storage area in Dong Ha after an artillery attack. Other men received Purple Hearts and Letters of Commendation for injuries and outstanding performance of duty under fire.

During the Dong Ha deployment, there were 128 enemy attacks on NMCB-11 camps in Dong Ha (98), Khe Sanh (3), Cua Viet (18), Lang Vei (7) and Gio Linh (2) with a total of five Seabees KIA and 52 Seabees WIA. One Seabee was killed in an enemy attack at Khe Sanh on 6 June and four Seabees were killed in an enemy attack at Dong Ha on 28 August There were also 6 road-mining incidents, three ambushes and one land-mine attacks with another 12 Seabees WIA. This deployment featured the most intensive enemy action experienced by any Seabee battalion since World War II. The Seabees of NMCB-11 lived through not only mortar and artillery attacks, but also assaults by Russian-made amphibious tanks at Lang Vei.  Members of the CIDG garrison managed to capture two of these enemy tanks near Lang Vei.
 
29 Nov - 7 Dec 1967 With construction work complete in Dong Ha, and being relieved by NMCB-5, the Battalion returned to CONUS on military and commercial aircraft and arrived at NAS Point Mugu for the short bus trip to Port Hueneme.  The various prop aircraft puddle-hopped across the Pacific stopping off for refueling in Midway, Wake and/or Hawaii on the flights back to CONUS.
 
December 1967 Seabee Team 1110 deployed to Can Tho and Long Xuyen, Vietnam, in late December 1967.

4 December 1967 At ceremonies aboard NCBC, Port Hueneme, senator V. L. Sturgeon, Aide to the Governor of California, Gov. Ronald Reagan, accepted custody of a California State Flag that had been flown over Camp Barnes' berthing areas in Dong Ha during the deployment.
 
5 December 1967 At Battalion ceremonies aboard NCBC, Port Hueneme, the Mayors of Port Hueneme, Oxnard, Camarillo and Ventura joined with the Commodore in officially "Welcoming Home" NMCB-11. The Battalion was presented a resolution passed by the City Council of the City of Oxnard.
 
7 December 1967 The final flight of NMCB-11 arrived at NAS Point Mugu signifying completion of the Battalion's 1967 deployment to Dong Ha. The Battalion commenced leave period, reconstitution and training for the next overseas deployment. Seabees honed their skills in CBAT Training in Port Hueneme, field exercise at Rose Hill and once again the two-week military training exercise in Camp Pendleton.
 
13 December 1967 CDR Keith Hartell, CEC, USN, Commanding Officer of NMCB-11, presented a California flag flown over Camp Barnes in Dong Ha, Vietnam, to then California’s Governor Ronald W. Reagan.  In ceremonies held in front of the California State Capital in Sacramento, California, the flag was raised at the Capital. After serving as the official display flag for two days, the flag was retired to a permanent display in the rotunda of the State Capital. Following the flag raising ceremony, Governor Reagan was made an honorary Seabee and member of NMCB Eleven by the Commanding Officer.
 
April 1968 Battalion prepares for deployment to Vietnam.  Sometime during 1968, the battalion’s plaque/symbol was changed. The thrown “11 dice” were eliminated, and the new circular symbol reflected a Seabee sitting on top of an enlarged “11”.  “U.S. Naval Mobile Construction Battalion Eleven” was centered and lettered across the top of the plaque; “U.S. Pacific Fleet” was centered and lettered across the bottom of the plaque. The words “Constructing the Future” were shown above the Seabee and below the NMCB-11 words. A wide yellow hawser (rope) surrounded the circular plaque.
 
16 April 1968 Battalion’s advance party landed in Quang Tri, Vietnam with 7 officers and 112 enlisted men.
 
5 May 1968 Homeport military training cycle was completed. Battalion deployed by USAF C-141 aircraft to the Philippines and shuttled aboard C-118 and C-130 aircraft from the Philippines to Quang Tri, Vietnam, to begin their third consecutive deployment to the war zone. Some of their personnel effects and heavier equipment was sent via ship. One of these ships was the SS Golden State that sailed on 30 March and arrived 30 April. The other was the USNS Sgt. Miller that sailed on 2 May and arrived on 1 June.

The last USAF C-130 shuttle aircraft from the Philippines crash landed on the runway in Quang Tri critically injuring seven NMCB-11 Seabees. Fortunately, there were no deaths. Several officers and enlisted men received Navy & Marine Corps, Navy Commendation or Navy Achievement Medals for their heroic actions in response to that crash incident.

Prior to their deployment, the North Vietnamese and Viet Cong had a “go for broke” campaign across South Vietnam known as the “Tet Offensive.” They simultaneously attacked multiple U.S. and Vietnamese positions throughout the country.  NMCB-11 entered country as this action was winding down.

Battalion first lived in a tent-camp pitched in the sand adjacent to Quang Tri airfield. During the first two months, the galley, mess-deck, and scullery were located in six tents with wooden decks. The blowing wind, sand and rain played havoc on the Battalion’s morale as they constructed a new camp on the other side of the airfield.  However, a very active recreation program made up for the lack of good facilities and enhanced the morale of the troops. Live entertainment was always welcomed.
 
30 May 1968 Seabee Team 1111 deployed first to Bung Kan and later to Thung Song, Thailand, near the Cambodian border. Seabee Team 1112 deployed first to Chiang Kham and later to Mae Chan, Thailand, near the Burma border.
 
17-30 June 1968 Between 17-30 June 1968, Battalion personnel completed and moved into their new camp. All shops and offices also moved, except Alpha Company Shops.  On June 30, a new 1,000-man galley was completed.  During the deployment, the galley supported between 900 to 1300 personnel depending on the number of assigned detachments.  This was the best camp the Bees had lived in during the first three deployments to Vietnam.  Further improvements were made daily.

Construction work included: “Operation Roadrunner” a 24-hour seven-day-a-week project to accelerate construction of the high-priority Ammunition Supply Point (ASP) at Quang Tri; operating rock-off load ramp and rock crusher site at Cua Viet; Minimum Essential Requirements “MER” project to upgrade camp support for Navy, Army and Marine forces in the Quang Tri Combat area; cantonment for the First Marine Air Wing site in Quang Tri; NMCB-11’s new camp site; the MAC-V Compound in Quang Tri City; support for Bravo Medical galley; support for the Army’s Surgical Unit huts; support for the Army camp at Hill 12; advanced base support for the Army’s First Air Cavalry and the 4th Regiment of the 5th U.S. Army Mechanized Brigade moving into the DMZ to relieve Marines for other support.

MER Project. High Priority. Five details consisting of over 200 Seabees from other deployed Seabee battalions—i.e., 1, 10, 71, 74, and 133—arrived in Quang Tri to assist NMCB-11 with the large high-priority “MER” Construction Project.

Roadwork.  High Priority.  NMCB-11 worked on bridge and road upgrade work on Vietnam Rt. 1 from Dong Ha to Quang Tri and Rt. 9 from Dong Ha to Cam Lo and west to the Rock Pile leading to Khe Sanh.  They joined Seabees from other 11 other battalions involved in making sure Vietnam Route 1 was kept open from Saigon to Dong Ha, just south of the DMZ.  The coordinated Seabee roadwork included the following twelve Battalions: NMCB’s 1, 4, 7, 8, 11, 53, 58, 62, 71, 74, 138 and 133.

Seabee teamwork on the MER and highway projects was at its best and emphasized the “One Naval Construction Force” concept in Vietnam
 
June 1968 GEN Creighton W. Abrams, Jr., USA, succeeded GEN William C. Westmoreland, USA, as Commander Military Assistance Command Vietnam (MAC-V) with headquarters in Saigon, Vietnam. RADM Elmo R. Zumwalt, USN, relieved RADM Kenneth L. Veth, USN, as Commander Naval Forces Vietnam (COMNAVFOR-V).
 
18 September 1968 The NMCB-11 Seabee camp was named Camp Rhodes in honor of LT Joseph Rhodes, CEC, USN, from NMCB-121, who was KIA in Vietnam in 1967. RADM Ace C. Husband, CEC, USN dedicated the Camp. In attendance were GEN Hill, CG MAG-39, and CAPT Albion W. Walton, Jr., CEC, USN, COM 32nd NCR.
 
December 1968 With construction work complete in Quang Tri, the Battalion returned to CONUS on USAF C-130 prop aircraft and arrived at NAS Point Mugu for the short bus trip to Port Hueneme.
 
8 December 1968 Eligible NMCB-11 personnel as part of the 32nd NCR were awarded the Navy Unit Commendation for the periods 1 August to 23 October 1967 and 6 May to 8 December 1968. (One award covers both periods).
 
January 1969 Arrived at homeport in Port Hueneme, for leave period, reconstitution and training for the next overseas deployment.  Whether a 10-week school, On the Job Training (OJT), Disaster Recovery Training (DRT), Seabee Team Training, Safe Driving, Specialized Training, weapons training at the Seabee Rifle Range at Point Mugu, a field exercise at Broom Ranch and the annual two-week evolution at Camp Pendleton, the men kept quite busy during the homeport period.  Battalion celebrated the 27th anniversary of the Seabees in March 1969.
 
June 1969 Homeport military training cycle was completed. During the end of June 1969 the Battalion’s families and friends gathered with the Seabees at the Pt. Mugu Naval Air Station waiting room. With a musical farewell by the CBC band and encouraged by pretty stewardesses the men began boarding the commercial aircraft for the long flights to Vietnam, Okinawa and Guam, depending on the ultimate destination.  Some of the men were beginning their fourth consecutive deployment to Vietnam in the war zone.  Seabee Teams 1113 and 1114 were deployed to the Trust Territories of the Pacific Islands in June 1969.
 
July 1969 A triple deployment site began for the Battalion. Battalion arrived in Vietnam and Okinawa during the last week of June 1969. Four aircraft arrived in Vietnam and one flight arrived in Okinawa. The battalion relieved NMCB-10 at Camp Evans, north of Hue, Vietnam. Their own Seabee camp was later named Camp Haines, in honor of EOC John C. Haines, Jr., of Bordentown, NJ, who was KIA March 7, 1967 while serving with NMCB-4, in Danang, Vietnam. Battalion later deployed a large detachment to Guam. About one-third of the battalion was deployed as a miniature battalion—Detachment Echo—on Okinawa. It was completely independent and self-sustaining unit with an officer in charge.
 
8 July 1969 Seabee Team 1113 deployed to Yap, and Seabee Team 1114 deployed to Majuro, both located in the Trust Territories of the Pacific Islands.
 
July – December 1969 Battalion worked on the following projects in Vietnam: roadwork on Rt. One from Phu Loc to Danang; Bridge 15A (240’ long) on Rt. One; raising fallen sections of a bridge damaged by Viet Cong crossing the Song Bo River, located five miles south of Hue; two timber bridges near Hue; reconstruction of a railroad bridge; operating the rock crusher site named “Bonnie & Clyde” run by Alpha Company; and other projects in the I-Corps Area.  Details were sent to work at L.Z. Nancy, L.Z. Sally, Song Bo, Phu Loc, Dong Ha, Saigon, Okinawa, Guam, and other locations.  The Battalion numbered some 1100 officers and men, the largest on active duty at that time.
 
28 July 1969 CDR Jack L. Godsey, CEC, USN, relieved CDR Hartell as commanding officer, NMCB-11.  Shortly after the change of command, it was announced the NMCB-11 would be returning to Port Hueneme, California, in late November and it would be decommissioned in December 1969 as part of the Presidents plan to reduce forces in Vietnam.
 
7 August 1969 Early in the morning of 7 August 1969 at Landing Zone Nancy (L.Z. Nancy), a U.S. Army Mortar Platoon was firing in support of a security patrol under fire outside the wire. Sparks from a mortar tube ignited nearby ammunition stores. Seven Seabees from NMCB-11 raced through darkness in an attempt to extinguish the flames. They fought the conflagration and prevented it from spreading. CM1 Milford M. Tognazzini, USN, was KIA by shrapnel from an exploding armored personnel carrier. Several of his fellow Seabees were WIA.

CM1 Tognazzini was posthumously awarded the Soldier's Medal for heroism, as recommended by U.S. Army military authorities, and a Purple Heart for injuries suffered during the incident.
 
August 1969 Typhoon “Cora” blasted Okinawa in Mid-August with no loss of life but caused major damage to infrastructure on Okinawa. Detachment Echo sprang to action on Okinawa to restore utilities and repair damage to buildings.
 
24 September 1969 Detachment Echo worked on various projects in Okinawa.  On 22 September they later split up the Detachment. On 24 September a portion of the Seabees deployed to Guam to do repair work on the Naval Station’s Bachelor Civilian Quarters, electrical transmission lines, and other smaller projects.
 
November 1969 In late November 1969, NMCB-11 began returning from Vietnam, Okinawa and Guam, to their homeport in Port Hueneme, California, to prepare for their decommissioning.  U.S. Army units relieved the Battalion at Camp Haines, Vietnam. The National Defense Service Medal was awarded to all eligible military men serving between 1 January 1961 and 14 August 1974. NMCB-11 was awarded the Navy Meritorious Unit Commendation for service between 1 January to 23 January 1969 and 16 April to 18 November 1969 (one award covered both periods).
 
20 December 1969 NMCB-8 and NMCB-11 were both decommissioned this date, at CBC, Port Hueneme, California.  This had been NMCB-11’s homeport for a little over 16 years since 1953. BM1 Theodore “Pappy” Hinson lowered the Battalion’s flag for the final time on December 15, 1969. It was fitting that he did so since he concluded four consecutive tours with the Battalion to Vietnam. NMCB-11's CDR Godsey presented Eleven’s flag to RADM Spencer R. Smith, CEC, USN, Commander, Construction Battalions, Pacific (COMCBPAC) for the last time. NMCB’s 5, 8, 10 and 11 passed in review on that solemn occasion as two proud and heroic Seabee battalions were decommissioned that day.  CDR Godsey departed NMCB-11 and became the Commanding Officer of NMCB-3.
 
December 1969 Seabee Teams 1113 and 1114 that were previously deployed to the Trust Territories of the Pacific Islands—Yap and Majuro—were transferred to NMCB-3 for operational control when NMCB-11 was decommissioned in December 1969. They reported to NMCB-3 in January 1970 when their tours were completed. They were the last two Seabee teams deployed by NMCB-11.
 
20 December 1969 NMCB-11 personnel serving in Vietnam were awarded the following Vietnamese military unit awards for service in Vietnam: Republic of Vietnam Meritorious Unit Citation, Civil Actions Medal, First Class Color, with Palm, for eligible periods of duty between 1 February 1966 and 19 January 1971; and, Republic of Vietnam Meritorious Unit Citation, Gallantry Cross Medal, with Palm for eligible periods between 1 April 1967 and 31 November 1969. One award covered all eligible periods for each medal/ribbon. Also, eligible personnel were authorized the Combat Action Ribbon for hazardous deployment work under fire or combat situations on an individual case-by-case basis for service between 1965 and 1969. One award covered all eligible periods. Also, eligible personnel were authorized the Vietnam Service Medal with Fleet Marine Corps Device, for any one of 12 eligible periods of service between 15 March 1962 and 30 April 1970.  One bronze campaign or battle star was awarded for each individual period of service.  One silver star could be substituted for five individual bronze stars.
