Three brothers and four of their sons will set off from Oxfordshire when they travel to Ukraine to deliver three ambulances.
The Watt family will begin their 1,500 mile journey to Lviv after launching their 1000 Lives campaign on Fathers’ Day.
The campaign's goal is to save 1000 lives by purchasing and delivering 1000 Individual First Aid Kits, essential equipment for handling life-threatening wounds. it is looking to raise £120,000.
Angus Watt, 60, who owns classic car company Greatworth Classics, based near Banbury, David Watt, 54, who runs CI Group, a marketing services business based in Banbury, and Chris Watt, 57, will be driving with sons Max, 19, Fynn, 23, James, 27, and Joe, 18.
Former Army Captain Chris Watt said: "I know from my own experience how important Individual First Aid Kits are and why they're needed.
"After serving myself I know that an Individual First Aid Kit can save a life.
"This has been a powerful motivation for me to support the 1000 Lives campaign."
The journey will be in support of Diving Ukraine, which was set up by Fynn Watt.
On the second anniversary of his involvement in the initiative, the three brothers have decided to come together for the journey.
Since the campaign was launched two years ago, it has delivered 110 vehicles to Ukraine and raised more than £600,000.
It has also saved many lives, evacuated hundreds of Ukrainians, provided aid, and enlisted hundreds of volunteers
Fynn Watt said: "In Ukraine, family relationships are so tight, especially at these trying times.
"I’m so proud to see my family come together and set an amazing example of what a family can do when they unite for a worthy cause.
"We appreciate not every family has the opportunity to do a journey like this but you can help with the 1000 Lives campaign. We need you.”
Angus Watt said: "We've all been supporting Driving Ukraine, and Fynn’s work individually, but for this we had to come together.
"That's why my brothers and I decided it wasn't going to be just us - it was going to be the whole Watt team."
David Watt added: "This mission is about more than aid; it’s about hope and solidarity.
"We are delivering more than just equipment; we are delivering a message of support and compassion to those who need it most.
“I’ve worked alongside Paralympic teams, I have seen and heard how disabilities can impact someone’s life.
"Our 1000 Individual First Aid Kit campaign wants to make sure fewer young Ukrainians experience that reality."
