At least 10 people have died and 10,000 properties have been damaged in the fires, and officials expect figures to grow as firefighters and first responders struggle to contain the flames.

The Santa Ana winds annually threaten to stoke the flames during California's wildfire season, but extreme drought combined with the powerful offshore winds catalyzed the record-breaking wildfires that continue to burn through Southern California.

Since California Gov. Gavin Newsom declared a state of emergency in Los Angeles County, tens of thousands of residents have been impacted by evacuation orders.

More than 600 personnel, 10 rotary-wing aircraft, and two C-130 Hercules aircraft from the California National Guard were deployed to battle the blaze.

The Biden administration ordered the Pentagon to send eight MAFFS-equipped C-130s from Nevada, Wyoming, and Colorado to support firefighting efforts in Los Angeles. Some were expected to start fire-suppression flights on Friday.

Hazardous weather conditions prevented the DoD from getting the planes in the air earlier and from sending additional assets to respond to the massive fires.

"We can surge assets, and the president has directed this department to bolster whatever California needs, but we have to work with California," Deputy Pentagon Press Secretary Sabrina Singh said during a press conference Wednesday, "and right now, we can't even get assets up in the air because the fires are so bad and the winds are so bad."

"Until we can get more assets in the air, there's only so much we can provide," she continued. "So we're going to be standing by to support in every single way that we can."

In the meantime, the Defense Department is also sending 10 Navy helicopters with water delivery buckets for immediate aerial suppression, in addition to two firefighting teams and four military police groups on the ground.

The Lockheed C-130 Hercules is a versatile workhorse plane with a spacious cargo hold that can be equipped for a wide range of operations.

When deployed as a firefighting aircraft, the C-130 can be equipped with a Modular Airborne Fire Fighting System (MAFFS) unit to support other air tankers in aerial suppression.

The MAFFS units can be filled with water or a fire retardant called "slurry," which is mostly made of water with the addition of ammonium sulfate, a jelling agent, and red coloring to make it visible to pilots when dropped.

The US military has eight MAFFs units ready for use nationwide, operated by National Guardsmen stationed in California, Nevada, Wyoming, and Colorado.

The MAFFS Program was launched by Congress in the 1970s after a massive wildfire in Long Beach, California, overwhelmed the responding civilian air tanker fleet and destroyed hundreds of homes.

The unit can fit inside the cargo hold with no structural modification to allow for quick loading on short notice, taking about four hours or less for a crew of five to set up, fill, and load the 11,000-pound unit.

The C-130 drops its contents through a discharge tube installed on the rear left side of the C-130 and through the open cargo bay door, releasing 3,000 gallons in less than five seconds and covering an area over 1,300 feet long and 100 feet wide.

Because the fire retardant slurry is released in a mist, it doesn't cause damage to buildings and structures while acting as a fertilizer, but it can be harmful to the environment and local wildlife if used in excess.

The unit can be refilled and airborne again in under 20 minutes.
